It is required to specify how many times a set of statements have to be executed, it is also called counter controlled loop.
Syntex :-
for(initialization; condition; increment/decrement){
//statement or code to be executed
}
Q.) W.A.P To Print The square root of a number in C++ ?
#include < iostream>
#include< math.h>
using namespace std;
int main()
{
float NO, answer_of_GivenNO;
cout <<"Enter number to find its squareroot: ";
cin >> NO;
answer_of_GivenNO = pow(NO, 0.5);
cout<<"Squreroor of "<< NO<<" is: " << answer_of_GivenNO << endl;
}
Output
Enter number to find its squareroot: 4
Squreroor of 4 = 2.
