Write a program to aceept 5 numbers from keyboard n print itz total?

User Avatar

Asked by Wiki User

Sure! Here's a simple Python program that allows the user to input 5 numbers and then calculates and prints their total:

numbers = []
for i in range(5):
    num = int(input("Enter a number: "))
    numbers.append(num)

total = sum(numbers)
print("The total is:", total)

This program prompts the user to enter a number 5 times, converts each input to an integer, stores them in a list, calculates the sum of the numbers using the sum() function, and finally prints the total.

What is the restriction to be followed when using a modulo operator modulo operator?

User Avatar

Asked by Wiki User

When using the modulo operator in mathematics or programming, there is a restriction that the divisor (the number after the modulo operator) should be non-zero. A zero divisor would result in a division by zero error, which is undefined.

C program to calculate the roots of a quadratic equation using two pointer parameters?

User Avatar

Asked by Wiki User

Here is an example of a C program that calculates the roots of a quadratic equation using two pointer parameters:

#include <stdio.h>
#include <math.h>

void calculateRoots(float a, float b, float c, float* root1, float* root2) {
    float discriminant;

    discriminant = b*b - 4*a*c;

    if(discriminant > 0) {
        *root1 = (-b + sqrt(discriminant)) / (2*a);
        *root2 = (-b - sqrt(discriminant)) / (2*a);
        printf("Roots are real and different.\n");
    } else if(discriminant == 0) {
        *root1 = *root2 = -b / (2*a);
        printf("Roots are real and the same.\n");
    } else {
        printf("Roots are complex and different.\n");
    }
}

int main() {
    float a, b, c, root1, root2;

    printf("Enter coefficients a, b, and c: ");
    scanf("%f %f %f", &a, &b, &c);

    calculateRoots(a, b, c, &root1, &root2);

    printf("Root 1: %.2f\n", root1);
    printf("Root 2: %.2f\n", root2);

    return 0;
}

In this program, the calculateRoots function takes the coefficients a, b, and c of the quadratic equation as well as two pointer parameters root1 and root2 to store the roots. It calculates the roots using the quadratic formula and updates the values pointed to by the pointers. The main function prompts the user to enter the coefficients, calls the calculateRoots function, and then prints the roots.

C program to detect occurrence of vowel with specification in given line text?

User Avatar

Asked by Wiki User

Here is a C program that detects the occurrence of a specified vowel in a given line of text:

#include <stdio.h>
#include <string.h>

int main() {
    char line[100];
    char vowel;
    int count = 0;

    printf("Enter a line of text: ");
    fgets(line, sizeof(line), stdin);

    printf("Enter the vowel to search for: ");
    scanf("%c", &vowel);

    for (int i = 0; i < strlen(line); i++) {
        if (line[i] == vowel || line[i] == vowel - 32 || line[i] == vowel + 32) {
            count++;
        }
    }

    printf("The vowel '%c' occurs %d times in the given line of text.\n", vowel, count);

    return 0;
}

This program reads a line of text from the user and prompts them to enter a vowel to search for. It then iterates through each character in the line, checking if it matches the specified vowel (both lowercase and uppercase). If a match is found, the count is incremented. Finally, the program prints the number of occurrences of the specified vowel in the given line of text.

Are a10 and 10a same in C language?

User Avatar

Asked by Wiki User

No, 'a10' and '10a' are not the same in the C language. In C, identifier names must start with a letter or an underscore, so 'a10' is a valid identifier, while '10a' is not.

How do we declare enmurated data type?

User Avatar

Asked by Wiki User

Enumerated data types can be declared using the enum keyword followed by the name of the enumeration and a list of possible values enclosed in curly braces. Each value is separated by a comma. For example, enum Color { Red, Green, Blue } declares an enumeration named Color with three possible values: Red, Green, and Blue.

What are chess timers for?

User Avatar

Asked by Wiki User

A chess timer or time clock is a device with two timing clocks side by side, one for each player. There is a button or plunger on the top of each timer. When one of the buttons or plungers is pressed, that timer stops running and automatically starts the other timer running. Depending on the situation or agreement between the players, the time period may vary. Its purpose is to either force players to make a minimum number of moves within a particular period of time or to make any type of move before the time runs out while it is that player's move. In official tournament matches the clocks are set for two and a half hours each with the requirement that each player must make at least 40 moves within that time. After that time, the game may go on with no further time restraints. In non-official games, the players may agree to any time period as they choose. For example, a "Blitz" game is usually 5 minutes long, but the purpose of the time period is not to force a certain number of moves within that time. A Blitz game is a kind of Musical Chairs on the chess board. If a player's time runs out while it is his/her move, that player loses. In informal games, the players may agree on any period of time. Many players love Blitz games for the rush of action that occurs as each player moves pieces almost by instinct rather than carefully thought out strategies There simply is no time for too much thought. There are two types of clocks. One is where the clock simply stops when the player presses the button/plunger. The other type is where the clock stops but backs up about 3 seconds. This is to compensate for the time it takes the player to move his/her hand from the moved piece over to the timer to stop his/her clock.

When only a copy of the argument's value is passed into the paremeter variable?

User Avatar

Asked by Wiki User

By default, a copy of the argument's value is passed into the parameter variable. This is "call by value" semantics, and the called function can do whatever it wants with the parameter, but it cannot alter the original copy. Sometimes, in C and C++, you can pass the address of the value instead. This is "call by address" semantics, but the called function must be designed to handle it - in this case, the called function can alter the original value. (Actually, it is always "call by value" - what we call "call by address" is simply passing the value of the address, a subtle distinction which is important to understanding the language.)
