How do you read more than one line in C?
#include <stdio.h>
#include <string.h>
/* To read something into a string in C you would do the following: */
char * str;
str = malloc(100 * sizeof(char));
scanf("%s", &str);
/* Another way to do the same thing is to read character by character: */
for(int i = 0; (i < 100) && (*(str + i) != '\n') ; i++)
scanf("%c", str + i);
/* This code told the computer to keep reading into str until the computer reads a '\n'
or until the computer reads 100 characters (which is how much I mallocated for str) */
/* Changing the '\n' to 'q' means keep reading and don't stop until you find a 'q'
These should work, if used correctly.
// stores srcL + srcR into dest
// NOTE: dest must be at least as large as srcL + srcR
void strConcat(const char* srcL, const char* srcR, char* dest) {
const int lengthL = strLength(srcL);
const int lengthR = strLength(srcR);
// copy srcL into front of dest
int i;
for(i = 0; i < lengthL; ++i) {
dest[i] = srcL[i];
}
// copy srcR into the rest of dest
for(i = 0; i < lengthR; ++i) {
dest[lengthL + i] = srcR[i];
}
dest[lengthL + i] = '\0';
}
// copies characters from src to dest
// NOTE: dest must be at least as large as src
void strCopy(const char* src, char* dest) {
const int length = strLength(src);
// copy
int i;
for(i = 0; i < length; ++i) {
dest[i] = src[i];
}
}
// reverses str and puts the result in buff
// NOTE: buff must be at least as large as str
void strReverse(const char* str, char* buff) {
const int length = strLength(str);
// special case for zero-length strings
if( length == 0 ) {
return;
}
// reversify
int i;
for(i = 0; i < length; ++i) {
buff[i] = str[length - i - 1];
}
buff[i] = '\0';
}
// returns the number of characters in str
int strLength(const char* str) {
int length = 0;
// take advantage of the fact that all strings MUST end in a null character
while( str[length] != '\0' ) {
++length;
}
return length;
}
Which of these statements is the most complete description of language?
language is any information communicated in written spoken or symbolic form
Define a complex number using c structure?
Just define two fields (whatever those are called in "C" - the parts of the structure), one for the real part, one for the imaginary part.

How do you make a speed calculator in c plus plus?
To calculate speed you need to know the distance travelled and the time taken to travel that distance such that Speed = Distance / Time. The result of this calculation gives the average speed without taking into account any periods of acceleration or deceleration. We can implement this using just one function:
long double speed (const long double distance, const long double duration) {
return distance / time; }
Note that we use the term "duration" rather than "time" purely to aid readability; "time" implies a specific moment in time rather than a duration.
We use a long double to cater for the widest possible range of values. However, if we want to ensure the most efficient calculation over a wide variety of numeric types, we would use a function template instead:
template<typename T>
T speed (const T& distance, const T& duration) {
return distance / duration;
}
The distance and duration variables will typically be taken from input:
int main () {
double distance, duration;
std::cout << "Enter the distance and duration: "
std::cin >> distance >> duration;
std::cout << "Speed = " << speed (distance, duration) << '\n';
}
Note that the actual units of measurement are not important to the function because speed is denoted by the given distance per given time unit. That is, if we travel 100 meters in 10 seconds, then the speed is 10 meters per second, whereas if we travel 100 miles in 10 minutes, then we are travelling at 10 miles per minute. Thus when distance is 100 and duration is 10, the speed is 10. It is up to the caller to convert these units to something more meaningful:
int main () { double distance, duration; std::cout << "Enter the distance in kilometers: ";
std::cin >> distance;
std::cout << "Enter the duration in hours: ";
std::cin >> duration;
std::cout << "Speed = " << speed (distance, duration) << " kilometers per hour\n";
}
Note that the examples do not perform any error-checking upon the input. In production code when entering numbers from input you will typically input strings instead. You will then test the strings are valid before typecasting the strings to a numeric format such as double.
How can an individual structure member be accessed in terms of its corresponding pointer variable?
By dereferencing the pointer variable. This can be achieved in two ways:
typedef struct s {
int i;
float f;
};
void f (struct s* p) {
int x = p->i; /* using pointer to member operator */
float y = (*p).f; /* using dereference operator */
}
The two methods are functionally equivalent.
Wap to calculate simple interest using c language?
ques : if principle amount is
>=10,000 then rate of interest is 20%
>=8,000 <=9999 then rate of interest is 18%
<+8,000 then rate of interest is 16%
Ans:
#include<stdio.h>
int main()
{
float si,p,t,r;
printf("enter principle amount & time");
scanf("%f%f",&p,&t);
if(p>=10000)
{
r=20;
}
else if(p>=8,000&&<=9999)
{
r=18;
}
else
{
r=16;
}
si=(p*t*r)/100;
printf("simple interest + %f",si);
return(0);
}
How can you use an array to find the product of 4 x 13?
You can do 4 rows and 13 columns and you get 52.
product = sizeof (char [4][13]);
of course it is just a joke, in actual code you write
product = 4*13;
What is the function of fast loop?
the flow through by pass flowmeter is known as fast loop or speed loop, to reduced the time lag between sample system and sample point.
How do you get your old iTunes library even if you replace it with another iTunes library?

What is the worst programming language?
There is no general answer to this question.
While some languages might be better to solve a certain problem than others, every language has its field of application. Some languages might be educational (LOGO) or entertaining (LOLCODE) but that are applications anyway. Even languages like COBOL or FORTRAN still have their uses. The question is not "better or worse", it's "How does it fit my requirements".
That said, there are language features which are bad in a way which is hardly debatable. For a discussion of some of these see:
What is the worst programming language you ever worked with? (http://stackoverflow.com/questions/961942/what-is-the-worst-programming-language-you-ever-worked-with)
C# is a general-purpose, block structured, procedural, imperative computer programming language that is just not meant to be used in serious enterprise applications.
Those good old all-capital languages (FORTRAN, BASIC, COBOL): programs written in them are practically unreadable.
Interrupt flags are used to interrupt the processor on what it is doing. When the flag is triggered the processor stops what it is doing attends what the flag wants to get done and once that is done it goes back to what it was doing. It is very useful for detect bug.
Why does a program reside in ROM in an embedded system?
If it resided in RAM, it would get lost when you power off the system.
What is a program that calculates the sum of any 5 digit integer number entered by user?
#include<iostream>
unsigned sum_of_digits(unsigned num)
{
unsigned sum = 0;
do
{
sum += num%10;
} while (num/=10);
return sum;
}
int main()
{
unsigned number = 12345;
unsigned sum = sum_of_digits (number);
std::cout << "Sum of digits in " << number << " is " << sum << std::endl;
}
