In programming, when you call a function you are actually initiating the function. You are telling the function to begin and perform any tasks.
1.Type the name of the function, followed by a list of parameters that the function is expecting.
2.If the function returns a value, be sure to assign that value to a variable.
The following example calls multiply_X_by_Y, and assigns the returned value to myValue.
int myValue; myValue = Multiply_x_by_y(15, 10); |
In addition, you can place variables in the parameter list. The function call will make a copy of the values stored in the variables, and pass the copied value in through the parameters.
main() { int myValue; int valOne; int valTwo;
valOne = 10; valTwo = 5;
myValue = Multiply_X_by_Y(valOne, valTwo); }
Multiply_X_by_Y(int x, int y) { int z; z = x * y; return(z); |
