Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
The following code does not work. What needs to be fixed? Retype the code and clearly label what needs to be done. You should only add one line of code.
#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;
double collegeFund(double payment, double interest, double years);
void calculateAndPrint(double payment, double interest, double years);
