Put negative sign - in front of the variable name.

To output the amount you had spent as a negative value, you could write the following:

int expenditure = 75; printf("Your balance has changed by %d.", -expenditure);

The minus sign will remind you that you've spent this money rather than gained it.

-expenditure doesn't change the value stored in expenditure-it's still 75. The value of the expression is -75.

#include <stdio.h> int main(void) { int expenditure = 75; printf("Your balance has changed by %d.", -expenditure); return 0;//from ww w . j av a 2 s . c om }
