What are some examples of loops in C plus plus?

Answer 1

The following example demonstrates all 4 loop structures in C++.

#include<iostream>

int main()

{

int i;

std::cout<<"For loop...\n"<<std::endl;

for(i=0; i<10; ++i)

std::cout<<i;

std::cout<<'\n'<<std::endl;

std::cout<<"While loop...\n"<<std::endl;

i=0;

while(i<10)

std::cout<<i++;

std::cout<<'\n'<<std::endl;

std::cout<<"Do-while loop...\n"<<std::endl;

i=0;

do

{

std::cout<<i;

}while( ++i<10 );

std::cout<<'\n'<<std::endl;

std::cout<<"Goto loop...\n"<<std::endl;

i=0;

again:

std::cout<<i;

if(++i<10)

goto again;

std::cout<<'\n'<<std::endl;

}

Output:

For loop...
