Displaying data

Error · #1 10-Jun-2005, 09:31

I'm trying to output data using nested for loops to display the content of 2D character arrays as follows

CPP / C++ / C Code:

void display()
{
	printf("Processing\n");


	for(i = 0; i = 20; i++)
	{
		for(j=0; j=11; j++) 
			printf("%c", name[j][i]);

		printf("\t");

		for(j=0; j=50; j++) 
			printf("%c", quest[j][i]);
		
		printf("\t");

		for(j=0; j=10; j++) 
			printf("%c", color[j][i]);

		printf("\t");
	} 
	printf("Print sucessful\n");
}

When I activate the function while running the program, I get an endless stream of spaces. Does anyone know what I'm doing wrong?

You have misunderstood the syntax of for statement. Please check the corrects syntax from web.
You probably want the for statement to be

CPP / C++ / C Code:

for(i=0; i<=20; i++ )
{
    // etc
}

I would think it might be like this.

CPP / C++ / C Code:

for ( i = 0; i < 20; i++ )
{
    // etc
}

Dave: Yes why not.
<20 makes the length a round number but it's still just guessing since you don't know what the original poster exactly wanted.
The point is that the original poster now understands to learn the correct syntax.

Nice to flimflam like this about inconsequential matters

Increases neatly our posts counter

I point it out because it is a very common error: going off the end of the array, undefined behavior, all that ("inconsequential" indeed).

It appears to be just that for this last post of yours.

Ok sorry, I take that back. Makes sense when you explain it from your point of view.
