Why my coding is not working?

Question

#include <stdio.h>

int main() {
int i, j, rows;
char ch;
printf("enter the number of rows\n");
scanf("%d",&rows);
printf("enter which character you want in pyramid \n");
scanf("%c",&ch);
for(i=1;i<=rows;i++)
{
for(j=1;j<=i;j++)
{
printf("%c\ ",ch);
}
printf("\n");
};

return 0;
}

Answer 1

It is working, you just have to enter the count and char adjacent to each other like this:

9c

...Gives you 9 rows of "c "

Note, it looks like scanf isn't really suitable for this purpose:
