    Reverse my input - help??

    New here and trying to solve a simple problem but getting stuck. If I input 10 separate integers, I would like the program to revers them for the output.
    Problem I'm having is at present this simple program will inly output 4 or 5 integers.
    Any ideas how to solve??

    Program so far:

    #include <stdio.h>
    int main()
      char a, b, c, d, e, f, g, h, i, j;
      printf("Integars in reverse order\n");
      printf("Input 10 integers: ");
      scanf("%c%c%c%c%c%c%c%c%c%c", &a, &b, &c, &d, &e, &f, &g, &h, &i, &j);
      printf("In reverse: %c%c%c%c%c%c%c%c%c%c", j, i, h, g, f, e, d, c, b, a);
       return 0;

    use a loop to request the integers, store the results in an array, print the array in reverse, or fill the array in reverse if you know how big it is already then just output it forwards.
    Or as it's C++ forum you are writing in use a vector anyhow unless there will always be the same amount of inputs

    Then start deciding if you want to study C or C++.

    Hint... since you are working with integers, trying using integers instead of chars.
