    Function calling

    I have a problem with rotating an array and assigning it to different variables. Please help me with this. This is wat i have done. I am a novice and please help me in this.
    Code:
    #include<stdio.h>#include<stdlib.h>
    #include<conio.h>
    #include<math.h>
    
    
    int n[16],a[16],n1[16],n2[16],n3[16],n4[16],n5[16],n6[16],n7[16],n8[16],n9[16],n10[16],n11[16],n12[16],n13[16],n14[16],n15[16],n16[16], c=0;
    int x[16],i,j,k;
    int rotate();
    main()
    {
          printf("Enter the input \n");
          for(i=0;i<16;i++)
          {
                           scanf("%d",&a[i]);
          }
          for(i=0;i<16;i++)
          {
                           printf("%d",a[i]);
          }
          for(i=0;i<16;i++)
          {
                          int p=rotate();
          }
          getch();
    }
    int rotate()
          {
          printf("\nThe array is now rotated by\n");
          scanf("%d",&j);
          for(c=0;c<j;c++)
          {
          while(c<j)
          {
                    k=a[0];
                    for(i=0;i<16;i++)
                    {
                                     a[i]=a[i+1];
                    }
                    a[15]=k;
                    c++;
          }
          }
          printf("Rotated array is\n");
          for(i=0;i<16;i++)
          {
          printf("%d",a[i]);                           
          }
          }

    What I am trying to do here is rotate the array of binary number I input and save the rotated output after each rotation. Then, I want to perform the autocorrelation of the obtained set of numbers. Can u please help me now? I have to submit the code by tomorrow..

    You need three operations to do a rotation: >> and | and <<. You shift one way by some number of bits and then shift the other way. The pipe operator can glue together your result. Congratulations, you have done 1 bit-wise rotation. You can use the tutorials on the main site to learn this in detail. Come back, with code closer to your actual goal, if you need further help.
