WAP to Compute the Sum of two Number by using Function

Statement of C Progream: This Program accepts two Integers and Computes their Sum via addnums() :
There are two methods to write this Program

1. NON ANSI style
2. ANSI style

1. NON ANSI style:

#include<stdio.h>
#include<conio.h>

void main()

{

int a , b , result;

clrscr();

printf(" Enter the value of two numbers\n");

scanf("%d%d" , &a , &b);

result = addnums(a , b);

printf(" sum of %d and %d = %d\n" , a , b , result);

}                                                      /* End of main */

/* Function to add two numbers */

int addnums( var1 , var2)

int var1 , var2;

{

int sum;

sum = var1 + var2;

return(sum);

}                                               /* End of Function */

Output:

Enter the value of two numbers

24

68

sum of 24 and 68 = 92

2. ANSI style:

#include<stdio.h>
#include<conio.h>

void main()

{

int a , b , result;

clrscr();

printf(" Enter the value of two numbers\n");

scanf("%d%d" , &a , &b);

result = addnums(a , b);

printf(" sum of %d and %d = %d\n" , a , b , result);

}                                                      /* End of main */

/* Function to add two numbers */

int addnums( int var1 , int var2)

{

int sum;

sum = var1 + var2;

return(sum);

}                                               /* End of Function */

Output:

Enter the value of two numbers

14

18

sum of 14 and 18 = 32

                                                                 That's All
