    lil problem, i'm an idiot

    ok why does my program not even allow me to enter in a character for the "c" variable?

    heres the code:

    #include <stdio.h>
         int board[30][30] = {{0}, {0}};
         int b_rows, b_cols;
         char gem[27];
         int gem_value[27];
         char c;
         scanf("%d%d", &b_rows, &b_cols);
         printf("Rows = %d Cols = %d\n", b_rows, b_cols);
         printf("Enter a Character: ");
         scanf("%c", &c);
         printf("%c", c);
         return 0;
    here's the output:

    4 5
    Rows = 4 Cols = 5
    Enter a Character:
    its not even allowing me to enter a character in, what simple thing am i missing?

    Look up flushing the input buffer.
    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah

    Must be reading the newline from your first scanf.

    see if doing the following works.

    printf("Enter a Character: ");
    scanf("%*c%c", &c);
    I haven't used a compiler in ages, so please be gentle as I try to reacclimate myself. :P
