/* Fig. 6.8: fig06_08.c
Histogram printing program */
#include <stdio.h>
#define SIZE 10

int main()
{
/* use initializer list to initialize array n */
int n[ SIZE ] = { 19, 3, 15, 7, 11, 9, 13, 5, 17, 1 };
int i; /* outer for counter for array elements */
int j; /* inner for counter counts *s in each histogram bar */
printf( "%s%13s%17s\n", "Element", "Value", "Histogram" );
/* for each element of array n, output a bar of the histogram */
for ( i = 0; i < SIZE; i++ ) {
printf( "%7d%13d ", i, n[ i ]) ;
for ( j = 1; j <= n[ i ]; j++ ) { /* print one bar */
printf( "%c", '*' );
} /* end inner for */
printf( "\n" ); /* end a histogram bar */
} /* end outer for */
return 0; /* indicates successful termination */
} /* end main */
What's the "%c" mean in the programming,
and how the Histogram know the "Value"'s value
Thanks
