    Please provide your code attempts before we offer help.
    Try not.
    Do or do not.
    There is no try.

    Multiplication Code

    CODE
    //multiplication table for the number 0<=10


    #include <stdio.h>
    int main()

    int num, product;

    for( num = 0; num<=10: num++ ) {

    for( product = 1;

    product = 0 * num);

    }

    printf( "product is %d/n", product);

    return 0;

    }

    Close.... have a look at this version which is based on your conventions:
    Code:
    #include <stdio.h>
    int main(void)
    {
        int num, product;
    
        for( num = 0; num<=10; num++ )
        {
            for( product = 0; product<=10; product++ )
                printf( "product of %d * %d is %d\n", product, num, product * num);
    
        }
        return 0;
    }
    ... and check the link in my signature for notes on how to use code tags.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    ... then simply change the existing printf() statement to output something suitable for a row, and add putchar('\n'); at the end of the outer loop to start a new line.

    You'll have to do this yourself... no point in me doing it for you, I already know how to code and don't want to spoil your learning experience

    Multiplication Code

    I'm new at this -- I've tried putting the rows and columns in printf but I continue to get errors; plus I'm not getting correct answers for my multiplication table. What am I doing wrong?

    Post your code+errors, and someone will help you. Don't forget to use code tags when doing so.
    When all else fails, read the instructions.

    You're not paying attention in class, or you didn't do your reading.

    Seriously, Hammer's right. If you give up this easily, you're never going to enjoy programming. It only gets more difficult.

    Multiplication Code

    //I need the multiplication table in rows and columns with answers. What's missing?

    Code:
    /*
    
    #include <stdio.h>
    
    int main()
    {
    	int num, product;
    
    	for( num = 0; num<=10;num++ ) {
    
    		for( product = 0; product<=10; product++)
    
    		
    	printf( "product of %d*%d is %d/n", product, num, product);
    	
    		
    	}
    
    	return 0;
    
    }
    
    */

    Anna, Please don't start new threads with the same topic.

    The printf() call in your code doesn't quite match my version, I suggest you double check it. (its not doing any multiplication)

    I'll expand on what I said before about the loops:

    - the inner loop will printf() a rows worth of data, so you must remove the newline character in your current code.
    - on the outer loop, add a new statement to print out a newline character just after the inner loop has completed. The command for this would be putchar('\n');
    When all else fails, read the instructions.
