C Language programs


1) write a c program to add two numbers.

#include<stdio.h>
void main()
{
int a,b,c;
printf("Enter the vales of a,b");
scanf("%d%d",&a,&b);
c=a+b;
printf("the value of c is %d",c);

}

output:

2)Write a c program to add digits of a given number.

#include<stdio.h>

void main()

{

int n,remainder,sum=0;

printf("Enter the number");

scanf("%d",&n);

while(n!=0)

{

remainder=n%10;

sum=sum+remainder;

n=n/10;

}

printf("the sum of %d is %d",n,sum);

}

Output:

3)Write a program to reverse the elements in the array.

#include<stdio.h>

void main()

{

int n,i,j,a[10],b[10];

printf("Enter the number of elements in array\n");

scanf("%d",&n);

printf("Enter the array elements\n");

for(i=0;i<n;i++)

scanf("%d",&a[i]);

for(i=n-1,j=0;i>=0;i--,j++)

b[j]=a[i];

for(i=0;i<n;i++)

a[i]=b[i];

printf("Reverse array is\n");

for(i=0;i<n;i++)

printf("%d\n",a[i]);

}

output:
