trouble with printf alignment

hi !
can someone help me with the printf alignment
when i run the code below , compare with price = 5 and price=50

the alignment is like

$5.00
$50.00

how do i change my code , so the alignment is like

$5.00
$50.00


code
__________________________________________________ __
#include<stdio.h>

int main(void){
float price = 5;
int quantity =3;
static char *documentfmt = "%-40s %8s %10s %10s\n";
printf(documentfmt, "Product Name", "Quantity", "Unit Cost", "Subtotal");
printf("-----------------------------------------------------------------------\n");
printf("%49d",quantity);
printf("%6s%.2f\n","$",price);
return 0;
}

They're kind of identical... if you need to use spaces use a tag like CODE (with brackets around it) to make the text typewriter style, or find a substitute. Spaces disappear automatically in vbb.

Anyway, you can use printf() format specifiers to buffer a number with spaces. For example:

printf("%8.2f", 111);

will display:

__111.00

where the _s represent spaces. The 8 means 8 total characters in the output string, buffering with spaces if necessary; the 2 means 2 digits after the decimal. Of course, that means that any dollar sign will be separated from the rest of the number by spaces, but there's no way around that.

Oooops



$50.00
$5.00

rather dollar sign assigned together (left alignment)

i want to have the last digit of the price alligned

emmm..........

i want

___$5.00
__$50.00

(___ is space)

rather than

$5.00
$50.00

You can't do that in one single call - but this seems OK

Code:

---

#include <stdio.h>

void foo ( double val ) {
    char buff[20];
    sprintf( buff, "$%.2f", val );  // format to 2dp and prefix with $
    printf( "%8s\n", buff );  // now pad to correct indentation
}
int main ( ) {
    foo( 50 );
    foo( 5 );
    return 0;
}
