Each of these functions must not contain input or output statements.

Explanation / Answer

#include <stdio.h>
#include<stdlib.h>
int days;
int compute1(int days){
int i,charge=0;
for(i=1;i<=days;i++){
if(i<=3){
charge=charge+450;
}
else{
charge=charge+350;
}
}
return charge;
}
int compute2(int days){
int i,charge=0;
for(i=1;i<=days;i++){
if(i<=4){
charge=charge+750;
}
else{
charge=charge+650;
}
}
return charge;
}
int compute3(int days){
int i,charge=0;
for(i=1;i<=days;i++){
if(i<=5){
charge=charge+950;
}
else{
charge=charge+800;
}
}
return charge;
}
int main()
{
int input,stay;

printf( "1. Standard Room " );
printf( "2. Double Room " );
printf( "3. Suite " );
printf( "Selection: " );
scanf( "%d", &input );
printf( "How many days youwant to stay! " );
scanf("%d",&stay);
if(stay<=0){
printf("bad input..exiting..bye");
exit(0);
}
switch ( input ) {
case 1:
printf("Amount to be paid =%d",compute1(stay));
break;
case 2:
printf("Amount to be paid =%d",compute2(stay));
break;
case 3:   
printf("Amount to be paid =%d",compute3(stay));
break;
default:
printf( "Bad input, quitting! " );
break;
}
