    Please help, about limits .h

    I try to compile this piece of code but i got error like this: error: ‘UNIT_MAX’ undeclared (first use in this function)

    my code:

    #include<stdio.h>
    #include<limits.h> /*for UNIT_MAX*/
    int main(void)
    {
    int i;
    unsigned u = UNIT_MAX;

    printf("The largest unsigned int is %u\n\n", u);
    for(i = 0; i < 10; ++i){
    printf("%u + %d = %u\n", u, i, u + i);
    }
    for(i = 0; i < 10; ++i){
    printf("%u * %d = %u\n", u, i, u * i);
    }
    return 0;
    }

    Not UNIT_MAX - UINT_MAX!

    And use those code tags (the # in the top of the advanced reply window), around your program.

    You are welcome.

    You don't use # around your code. Instead, click on the # icon in the top bar of the advanced reply window, and IT puts the two code tags onto the page. Then just paste your code between the provided [..code] <code goes here> [../code] tags.

    Then your code will look like code, instead of squished html text. Much better for studying.
