return total_charge;

}

Explanation / Answer

The Modified program given below:

#include<stdio.h>
double total_charge(double h, double c);
void main()
{
double calc;
double hours,charge;
clrscr();
printf(" hours worked: ");
scanf("%ld", &hours);
printf("charges of cleaning per hour: ");
scanf("%ld", &charge);
calc = total_charge(hours,charge); //trying to call the function and ask for receive the value
printf("Total charge is %ld", calc);
getch();
}
double total_charge(double h,double c)
{
double tcharge;
tcharge=h*c;
return tcharge;
}

hi if you want to make read as a user defined function then u need to put hours and charge variables as global variables then only they can access in both main and read functions.then the code will be as follows:

#include<stdio.h>
double total_charge(double h, double c);

void read();

double hours,charge;
void main()
{
double calc;
clrscr();

read();
calc = total_charge(hours,charge); //trying to call the function and ask for receive the value
printf("Total charge is %ld", calc);
getch();
}

void read()

{

printf(" hours worked: ");
scanf("%ld", &hours);
printf("charges of cleaning per hour: ");
scanf("%ld", &charge);
}
double total_charge(double h,double c)
{
double tcharge;
tcharge=h*c;
return tcharge;
}
