Can you possibly provide the code for the while(){} and do {} while() code blocks? You're looping infinitely because you're not meeting the condition that breaks you out of the loop, most likely

This is my new code to my program


#include <iostream.h>
#include <string.h>
#include <stdlib.h>
#include <iomanip.h>

int x;
char st_name[25];
char st_address[75];
char st_color[25];
float f_ccost;
float f_acost;


void getdata();
void processdata();
void putdata();


int main()
{
while(x = 0 && x < 3)
{
getdata();
processdata();
putdata();
}
}
void getdata()
{
cout << "\n\nPlease enter your name: ";
cin.getline(st_name,25);

cout << "\n\nPlease enter your address: ";
cin.getline(st_address,75);

cout << "\n\nPlease enter the amount you paid for your car: ";
cin >> f_acost;

cin.get();

cout << "\n\nPlease enter your car color: ";
cin.getline(st_color,25);
}
void processdata()
{
cout << "\n\nCalculated amount of your car is: ";

if(f_acost < 1200)
{
if(strcmp(st_color,"blue")==0)
{
f_ccost = f_acost + f_acost*10/100;
cout << f_ccost;
}
else
{
cout << f_acost;
}
}
else if(f_acost > 1000 && f_acost < 1500)
{
if(strcmp(st_color,"black")==0)
{
f_ccost = f_acost + f_acost*20/100;
cout << f_ccost;
}
else
{
f_ccost = f_acost;
cout << f_ccost;
}
}
else if(f_acost <= 2000)
{
if(strcmp(st_color,"white")==0)
{
f_ccost = f_acost - 500;
cout << f_ccost;
}
else
{
f_ccost = f_acost;
cout << f_ccost;
}
}
else
{
f_ccost = f_acost;
cout << f_ccost;
}

}
void putdata()
{
cout << "\nPerson Name: " << st_name;
cout << "\nAddress: " << st_address;

cout << setiosflags(ios::fixed)
<< setiosflags(ios::showpoint)
<< setprecision(2);
cout << "\nActual Cost of Car: $ " << f_acost;
cout << "\nCalculated Cost of Car: $ " << f_ccost;
cout << "\nColor of Car: " << st_color;


}

Greetings,

The while loop operates as follows: The condition in parenthesis is tested. If it is true, the body of the loop is executed. Then the condition is re-tested, and if true, the body is executed again. When the test becomes false the loop ends, and the execution continues at the statment that follows the loop.

By contrast the do-while loop tests at the bottom after making each pass through the loop body. The body is always executed at least once. Here are the following syntax: The statment is executed, then expression is evaluated. If it is true, statment is evaluaged again, and so on. When the expression becomes false, the loop terminates.

Using a while loop in our case would not be difficult. It seems like you are wanting to do a while loop inside a do-while loop. The infinite loop for while would contain 1. 1 usually means true, and 0 determines false. Calling something like: Will never end, unless broken by other means, such as break and return.

In this case, we could do somewhat the following: The reason this works is because we infinitely call our do-while loop, though it only goes by once. Our while(1) calls on break once our do-while loop is finished. i increments 3 times before the do-while is over, hence (i < 3), and once that is over it continues to resume after our loop statement; which is break.


Hope this helps,

Hopeolicious,


you are infinitely looping because first you are setting "x equal to 0" which is a TRUE statement and then you are ANDing it to the condition "x less then 3" which is also a TRUE statement because you've set "x equal to 0." This has put you into the infinite loop because the condition for looping is always TRUE

x = 0 && x < 3 will resolve to TRUE in boolean algebra

What you conceptually have is,
