Program in C to add numbers using call by reference
This program in C will accept 2 numbers and perform addition of two numbers using call by reference method.
The below program accepts 2 numbers from the user and stores the value in num1 and num2. The program then makes a call to add function. We are passing address/reference of num1 and num2 as function parameters and hence the name, call by reference (also known as – pass by reference)
#include <stdio.h>
#include <stdlib.h>
int main(){
int num1, num2, result;
/*Accept the numbers from the user*/
printf("\nEnter the two number: ");
scanf("%d %d", &num1, &num2);
/* Pass the value of num1 and num2 as parameter to function add.
The value returned is stored in the variable result
*/
result = add(&num1, &num2);
printf("\nAddition of %d and %d is %d", num1, num2, result);
}
/*Defining the function add()*/
int add(int *no1, int *no2)
{
int res;
res = *no1 + *no2;
return res;
}
Output:
Enter the two number: 10 20 Addition of 10 and 20 is 30
please post more programs.. mostly with pointer..
i want to write every program with ponters….
thanx author.really help me
Write a program to find out the table of a given no. using array of structure….pls answer this question
#include
#include
void table(int n,int start,int end)
{
int i;
for(i=start; i<=end; i++)
printf(“%d x %d = %d \n”,n,i,n*i);
}
main ()
{
int n,start,end;
printf(“enter table to generate:\n “);
scanf(“%d”,&n);
printf(“from which number you want to start your table:\n”);
scanf(“%d”,&start);
printf(” At which number you want to end your table:\n “);
scanf(“%d”,&end);
table(n,start,end);
getche();
}

We can use pointers to add two numbers. We will pass base address of both operand.
very nice example
