Sum of two numbers in C Language Program Source Code Free with Explanations...

// Sum of two numbers in C Language Program Source Code :-
#include<stdio.h>
#include<conio.h>
void main()
{
int num1,num2,sum_num; // int means integer variable declaration
clrscr(); // clear the screen
printf("Enter First integer number :");
scanf("%d",&num1); // %d is to read an integer number from keyboard
printf("Enter Second integer number :");
scanf("%d",&num2);
sum_num=num1+num2; // calculating sum of given numbers
printf("Sum of %d and %d = %d",num1,num2,sum_num);
getch(); /* it is used for to wait the output screen upto getting any character from keyboard */
}

/* Save file as "anyname.c" and Run using Ctrl+F9.
Example:-
If first number is given 23 and second number is given 57 then the output will be as :-
Sum of 23 and 57 = 80

How to create User Defined Functions in C, see example Perfect_Number() function used as UDF in C Program

How to create User Defined Functions in C, see example Perfect_Number() function used as UDF in C Program :- Example : This is a program to find Perfect Numbers upto a limit using User Defined Function(UDF) in C Program Language :- #include<stdio.h> #include<conio.h> int Perfect_Number(int); /* UDF function prototype declaration : int argument and int returns */ main() { int lmt,num; clrscr(); printf("Enter a Limit :"); scanf("%d",&lmt); for(num=5 ; num<=lmt ; num++) { /* function calls here with Actual Parameter num and returns either 1 or 0 and checks */ if(Perfect_Number(num)==1) { printf("\n%d",num); } } getch(); } /* Either the function should be defined out side the main() or it should be in one of the header files included. function definition with a Formal Parameter as n */ int Perfect_Number(int n) { int a,sm; sm=0; for(a=1 ; a<n ; a++) { if(n%a==0) { sm=sm+a; } } if(sm==n) return 1; else ...
