Thread: Question about strings in c

Hey,
this is my code

Code:

for (k = 1; k < 15; k++) {		/*convert to binary*/
            putchar(number & displayMask ? '1' : '0');
            number <<= 1;
}

where number is an integer.
now this would display the binary form of number to stdout.
How would I assign that value to a string instead of displaying it?

thanks

I would have modified your code and just given you the answer had your code been correct to begin with.

You reap the benefits of my boredom...

Code:

#include <stdlib.h>
#include <stdio.h>

void Parse(int numb, char ** string);

int main()
{
	char * string = (char*)malloc(sizeof(char) * 50);
	if (!string) return 0;
	
	int number = 9784;
	
	Parse(number, &string);
	printf("&#37;s\n", string);
	
	free (string);
	return 0;
}

void Parse(int numb, char ** string)
{
	int i;
	int j = sizeof(numb) * 8;
	for (i = 0; i < sizeof(numb) * 8; i++, j--)
		(*string)[i] = (char)(((numb >> (j - 1)) & 1) | 0x30);
	(*string)[i] = '\0';
	printf("%d\n", i);
	return;
}

What is your assignment?

Oh cool. I'm assuming it's a university assignment?

If it's up somewhere I'll take a look at it, see if I notice anything blatant.

Alright well...
Just PM it.

I'll take a look when I get a chance (probably now lol).
