Anyone is there to explain me the logic of the If-else stated in this programme?

Question

#include <stdio.h>
void main()
{
int j,i,n;
printf("Input upto the table number starting from 1 : ");
scanf("%d",&n);
printf("Multiplication table from 1 to %d \n",n);
for(i=1;i<=10;i++)
{
for(j=1;j<=n;j++)
{
if (j<=n-1)
printf("%dx%d = %d, ",j,i,i*j);
else
printf("%dx%d = %d",j,i,i*j);

}
printf("\n");
}
}

Answer 1

They usually arent.

if (j<=n-1)
just says if j is less than or equal to n minus one.

THEY do, however almost use the same format to print wich is probablly what gets you. Look at the first one and how it prints a comma after the product of the 2 numbers. The "else" part has no comma. Most likely for appearence so the table looks nice.

Answer 2

What exactly dont you understand? What lines and why?

Answer 3

Slick why the statement of if and else are same?
