C Programming exercise with array. Find a value (number) in array and remove it. Compilation is Dev-C ++. Code:
  1. #include <stdio.h>
  2. #include <conio.h>
  3. int nhapmang(int a[100], int n)
  4. {
  5.     int i;
  6.     for(i=0;i<n;i++)
  7.     {
  8.                     printf("Element %d: ",i);
  9.                     scanf("%d",&a[i]);
  10.     }
  11. }
  12. int inmang(int a[100], int n)
  13. {
  14.     int i;
  15.     printf("Array: ");
  16.     for(i=0;i<n;i++)
  17.     {
  18.                     printf("%4d",a[i]);
  19.     }
  20. }
  21. int demsophantu(int x, int a[100], int n)
  22. {
  23.     int d=0, i;
  24.     for(i=0;i<n;i++)
  25.     {
  26.                     if(a[i]==x)
  27.                     {
  28.                                d++;
  29.                     }
  30.     }
  31.     return d;
  32. }
  33. int main()
  34. {
  35.     int a[100],d,x,n,i,j;
  36.     A:
  37.     printf("\n\nNumber of array elements: ");
  38.     scanf("%d",&n);
  39.     nhapmang(a,n);
  40.     inmang(a,n);
  41.     printf("\nEnter a value wants count and delete: ");
  42.     scanf("%d",&x);
  43.     d=demsophantu(x,a,n);
  44.     printf("%d have %d in array.\n",x,d);
  45.     for(i=0;i<n;i++)
  46.     {
  47.                     if(a[i]==x)
  48.                     {
  49.                                for(j=i;j<n;j++)
  50.                                {
  51.                                                a[j]=a[j+1];
  52.                                }
  53.                                i=i-1;
  54.                     }
  55.     }
  56.     printf("Array after deleteing %d: ",x);
  57.     for(i=0;i<n-d;i++)
  58.     {
  59.                     printf("%4d",a[i]);
  60.     }
  61.     getch();
  62.     goto A;
  63. }
