In this C++ tutorial, you will learn how to write a program to read a number entered by user, and print it to standard output.
C++ Print number entered by user
To print a number entered by user in C++, read the number from user using cin, store this number in a variable, and then print this number to output using cout.
Program
In the following program, we read a number to n from user via console input, and print this number to console output.
