C++ Do While Syntax

Elements of a c++ do while loop do { statement(s); } while( condition ); #include <iostream> int main(){ int userCounter = 0,cnt=0; std::cout << "how many times should we loop ?\n"; std::cin >> userCounter; do { std::cout << "Counting to " << userCounter << " now in the loop for " << cnt + 1 << " times\n"; cnt++; }while( cnt < userCounter ); } So Line 13...

C++ While loop example

As part of the flow control, we will write a c++ while loop example then examine its elements. #include <iostream> int main(){ int cnt = 0; bool isReady = true; while( isReady ){ std::cout << "Are we really in a loop\n"; ++cnt; if ( cnt > 5 ) isReady = false; } } Line 9. Does the c++ while loop example really loop only 5 times? C++ Loop Code Example So, did everything run ok? I see the...

C++ Flow Control if else switch case syntax – steal our code

There are a number of flow control syntax constructs in C++. They are basically the same as those in C, so if you are a C programmer you can skip this section. The c++ flow control constructs involve variations of : if, if else if syntax, while(isTrue) ..., do ... while(isTrue) and my favorite ...c++ switch case syntax ...with variations of continue, break and default c++ Flow Control Code...
