CPNM LAB PROGRAM-2

cpnm lab 2 programming made by ece the wonders ***THANK YOU***

----------------------------------------------

2. Write a program, which generates 100 random integers in the range of 1 to 100. Store them in an array and then print the arrays. Write 3 versions of the program using different loop constructs. (e.g. for, while, and do while).

----------------------------------------------

#include <stdio.h>

#include <stdlib.h>

int main()

{

  int n,i=1,a[100];

printf("choose the program type option:- 1=for,2=while,3=do while :");

scanf("%d",&n);

switch (n)

{

   case 1:

     

       {   printf("generate random numbers from (1-100) using 'for' loop\n");

             

           printf("----------------------------------------------------\n");

             

for (i=0;i<100;i++)

{ 

a[i]=1+rand()%99;

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

}

break;

          }

    case 2:

  { printf("generate random numbers from (1-100) using 'while' loop\n");

             

         printf("-------------------------------------------------------");

             while(i<=100)

{   

                    a[i]=1+rand()%99;

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

                  i++;    }

          break; 

        }

case 3:

          

        { printf("generate random numbers from (1-100) using 'do while' loop\n");

             

         printf("-------------------------------------------------------");

             do

{   

                   a[i]=1+rand()%99;

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

                  i++;  }

                 while(i<=100);

          break; 

        }

        

    }

        return 0;

        }
