    preprocessor!!

    i was typing a simple code in my c ide,i got stuck through a problem, plz help me out!!






    Code:
    #inlcude <stdio.h>
    main()
    {
    
    for (x=1; x<10; x++);
    	 printf("%d\n",x);
     }

    i got the rror message, Compiling NONAME02.CPP:
    Error NONAME02.CPP 1: Unknown preprocessor directive: 'inlcude'
    Error NONAME02.CPP 5: Undefined symbol 'x' in function main()
    Error NONAME02.CPP 6: Call to undefined function 'printf' in function main()
    Warning NONAME02.CPP 7: Function should return a value in function main()

    It is just a typo error. "#inlcude <stdio.h>" should be "#include <stdio.h>", or "#inlcude <cstdio>".

    Of course, other potential problems include:
    1. a missing return type for main (should be int)
    2. x is used without being declared
    3. the for loop has a semi-colon that makes the loop do nothing.

    you probably also want to remove the last semicolon on the for() loop line

    It is called copy and paste error, not typo error

    just to summarize things said above, here is the (hopefully) correct code:

    Code:
    #include <cstdio>
    int main()
    {
    for (int x=1; x<10; x++)
    	 printf("%d\n",x);
    }
