Thread: Multiplication Code

//please provide code for multiplication table

Please provide your code attempts before we offer help.

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;

}

/Code

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.

Thanks for your help -- but I need the mulitiplication table displayed in rows and columns.

... 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

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?

>What am I doing wrong?
Post your code+errors, and someone will help you. Don't forget to use code tags when doing so.

//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');
