Question

Write and test a program to rotate values in an array of 10 integers to the left by 1.

Use rand and srand to generate the array with random integers.

Example:

input; [34, 57, 89, 54, 11, 20, 21, 99, 23, 72]

Output : [57, 89, 54, 11, 20, 21, 99, 23, 72, 34]

Answer 1

#include <stdio.h>
#include <stdlib.h>
#include<time.h>
int main(){
   int nSize,i;
   printf("Enter size of numbers : ");   //taking size of numbers
   scanf("%d",&nSize);
   int Rarray[nSize];
   srand(time(0));
   //creating array with random numbers
for(i=0; i<nSize; i++)
   Rarray[i]=rand();
printf("Random generate Array :\t");
//displaying generated random numbers array
for(i=0;i<nSize;i++){
       printf("%d ",Rarray[i]);
}
printf("\n");
    //left rotating code
Rarray[nSize]=Rarray[0];
   for(i=0; i<=nSize; i++){
       Rarray[i]=Rarray[i+1];
   }
   //After left rotating displaying array
   printf("After left rotate,Array : ");
   for(i=0;i<nSize;i++){
       printf("%d ",Rarray[i]);
}
return 0;
