Checking the input character by character is the easiest way to determine that. int main() { int n; cout << "Press Enter to proceed...\n"; while ( n = cin.get() ) { if ( n == (int)'\n' ) { cout << "Carriage return and line feed encountered\n"; break; } else { cout << "Program is terminating...\n"; exit(EXIT_FAILURE); } } // rest of the program... } Sample input 1: Press Enter to proceed... dsg564sd6g46 Program is terminating... Sample input 2: Press Enter to proceed... Carriage return and line feed encountered

use getch()..... the output screen will wait for a key to enter(preferably Return) P.S. you can try this format but I am afraid it would work char ch ; cin>>ch ; if(ch=='\r') cout<<"User entered Return key" ;

" I think instead of cin.get() we can use getch() its better" You're totally wrong. `getch()` is a deprecated function from the long-dead header file <conio.h> in "C" language which no longer being used (and supported) for getting single characters. Instead, as your question tag emphasizes, you should look for the equivalent solution in C++. Also, the adjective "better" is a relational term. A "better" solution for problem A might be a "worse" solution for problem B.

You might be right, but bro I need just a single character so therefore I thought it would be better
