C++ While loopIn C++, while loop is used to iterate a part of the program several times. If the number of iteration is not fixed, it is recommended to use while loop than for loop. while(condition){ //code to be executed } Flowchart: C++ While Loop ExampleLet's see a simple example of while loop to print table of 1. #include <iostream> using namespace std; int main() { int i=1; while(i<=10) { cout<<i <<"\n"; i++; } } Output: 1 2 3 4 5 6 7 8 9 10 C++ Nested While Loop ExampleIn C++, we can use while loop inside another while loop, it is known as nested while loop. The nested while loop is executed fully when outer loop is executed once. Let's see a simple example of nested while loop in C++ programming language. #include <iostream> using namespace std; int main () { int i=1; while(i<=3) { int j = 1; while (j <= 3) { cout<<i<<" "<<j<<"\n"; j++; } i++; } } Output: 1 1 1 2 1 3 2 1 2 2 2 3 3 1 3 2 3 3 C++ Infinitive While Loop Example:We can also create infinite while loop by passing true as the test condition. #include <iostream> using namespace std; int main () { while(true) { cout<<"Infinitive While Loop"; } } Output: Infinitive While Loop Infinitive While Loop Infinitive While Loop Infinitive While Loop Infinitive While Loop ctrl+c
