swap (int *a, int *b) { *a ^= *b; *b ^= *a; *a ^= *b; }
using function we can call the function in the program any where. by using functions we can reduce the code redundancy
program to find maximum of two numbers using pointers
A program which is used to count the number of numbers in an array using a 8085 microprocessor is known as a assembly language program.
write a program that reads a phrase and prints the number of lowercase latters in it using a function for counting? in C program
Not possible. Let's not forget than in C the followings are all operators:+, -+=, -=++, --=&, *, []function-call
#include<
USING STRING LITERAL VALUES TO ADD 2 NUMBERS If you just want to show the outcome of two numbers you have: PRINT 4 + 5 This will print '9' the answer to 4 + 5. If you want to show the addition: PRINT "4 + 5 = "; 4 + 5 This will show the question and then calculate the answer. If you want the user to input numbers to add, use variables and then add them the same way. ====== COLLECTING USER INPUT FROM THE KEYBOARD/USING NUMERIC VARIABLES In the following example, the end user can get to interact with the program by typing in their numbers at the keyboard; then, pressing the [Enter] key. CLS PRINT "PROGRAM: Add 2 numbers" PRINT INPUT "Enter the 1st number: ", number1 INPUT "Enter the 2nd number: ", number2 PRINT sumTotal=number1+number2 PRINT "The sum total is: "; sumTotal PRINT INPUT "Again, Y/N"; yesNo$ IF UCASE$(LEFT$(yesNo$,1))="Y" THEN RUN END ====== CREATE FUNCTION/THEN, MAKE A FUNCTION CALL TO ADD 2 NUMBERS Another way to write this program is to create a function/then, make a function call... '*** PROGRAM: Add 2 numbers... '*** Variable declaration list... number1=7 '...initialise numeric variable 1 number2=3 '...initialise numeric variable 2 '*** Main program... CLS '...(CL)ear the (S)creen PRINT add(number1,number2) '...make function call/passing in 2 numbers to add END '...END of program/halt program code execution '*** Function(s)... FUNCTION add(num1,num2) '...this line marks the start of the Function add=num1+num2 '...this line returns the sum total of the 2 numbers END FUNCTION '...this line marks the end of the Function
int sum(n) { if (n==0) return 0; else return n+sum(n-1); }
extensible means to enhance the program with new capabilities. In c++, extensibility can be achieved by using virtual function. now first we discuss what is virtual function in c++. " C++ virtual function is a member function of a class, whose functionality can be over-ridden in its derived classes. The whole function body can be replaced with a new set of implementation in the derived class." Through this u can be able to promote extensibility in your program by using Virtual function. Very simple concept.
