    Converting an int into a char

    Good day!
    I have this problem: I have a number (int) and I want to know who's simbol's ASCII code is.

    From letter to number works well:
    Code:
    char s[10];
    int i;
    for(i=0;i<strlen(s);i++)printf("%d",s[i]);
    How should I find the simbol after my int?

    Assuming it is a single digit number, add it to '0'. The digits '0' through '9' are guaranteed to be in order. That will give you a character and you can get the value of the symbol from that in the same way you did above.

    So you have a number, say 65, and you want to see what character that represents? Just print it with %c:
    Code:
    printf("%c", 65);
    or putchar():
    Code:
    putchar(65);
    You might want to print a '-' or something if the character isn't printable:
    Code:
    #include <ctype.h>  /* for isprint() */
    
    if(isprint(c)) putchar(c);
    else putchar('-');
    Some characters can't be printed, or won't show up properly if they are.

    BTW, this is the C++ forum, not the C one.
