While and Do While Help

[hopeolicious]

I have to use a while loop to display everything 3 times and then i have to use a do while loop to do the same thing
when i added my while and do while loop it keeps on repeating like a millions times and i cant stop it can someone please help me

// Description: Display person name, address, calculated and
// actual cost of car and color of car

#include
#include
#include
#include

int x;
char st_name[25];
char st_address[75];

float f_ccost;
float f_acost;

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

int main()
{
for(x=1;x<=3;x++)
{
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);

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

[hopeolicious]

This is my new code to my program

#include
#include
#include
#include

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:

while (expression)
	statement

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 thedo-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:

do {
	statement
while (expression);

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 awhile 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:

while (1)
	statement

Will never end, unless broken by other means, such as break and return.

In this case, we could do somewhat the following:

int i=0;

// Infinite loop
while (1) {
	// Loop three times [i < 3]
	do {
		// Do stuff
		i++;	// Be sure to increment, or loop will never terminate.
	} while (i < 3);

	break;	// Break infinite loop
}

The reason this works is because we infinitely call ourdo-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,

while(x = 0 && x < 3)
{
   getdata();
   processdata();
   putdata();
}

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,

while(true) 
{
  getdata();
  processdata();
  putdata()
}
