 Write a program to reverse a number.

#include <stdio.h>

int main()

{

    int no, rev = 0;

    printf("\n Enter No to make it Reverse : ");

    scanf("%d", &no);

    while (no > 0)

    {

        rev = (rev * 10) + (no % 10);

        no = no / 10;

    }

    printf("\n Reverse of entered no is : %d", rev);

    return 0;

}

Write a program to generate first n number of Fibonacci series.

#include <stdio.h>

int main()

{

    int no = 10, i = 0, j = 1;

    printf(" %d %d", i, j);

    while (no > 0)

    {

        printf(" %d", i + j);

        j = i + j;

        i = j - i;

        no--;

    }

    return 0;

}

Write a C program to find the sum and average of different numbers which are accepted by user as many as user wants.

#include <stdio.h>

int main()

{

  int no,sum=0,i=0,val;

  printf("\n How Many Number You Want to Enter : ");

  scanf("%d",&no);

    while(i<no)

        {

          printf("Enter No [%d]:",i+1);

          scanf("%d",&val);

          sum=sum+val;

          i++;

        }

    printf("\n Sum = %d",sum);

    printf("\n Sum = %.2f",((float)sum)/no);

    return 0;

}

Write a program to check whether the given number is prime or not

#include<stdio.h>

int main() {

  int no, i;

  printf("\n Enter No to check wheather its prime or not :");

  scanf("%d", & no);

  for (i = 2; i < no; i++) {

    if (no % i == 0) {

      printf("\n %d is not prime", no);

      break;

    }

  }

  if (no == i) {

    printf("\n %d is prime", no);

  }

  return 0;

}
