a program demonstrates assignment operator in C

#include 
void main()
{
    int x = 10;
    
    /* demonstrate = operator */
    int y = x; 
    printf("y = %d\n",y);
 
    /* demonstrate += operator */
    y += 10;
    printf("y += 10;y = %d\n",y);
    /* demonstrate -= operator */
    y -=5;
    printf("y -=5;y = %d\n",y);
 
    /* demonstrate *= operator */
    y *=4;
    printf("y *=4;y = %d\n",y);
 
    /* demonstrate /= operator */
    y /=2;
    printf("y /=2;y = %d\n",y);
   
}
