Declare Multiple Variables
To declare more than one variable of the same type, use a comma-separated list:
Example
int x = 5, y = 6, z = 50;
printf("%d", x + y + z);
You can also assign the same value to multiple variables of the same type :
Example
int x, y, z;
x = y = z = 50;
printf("%d", x + y + z);
