create a variable in C++

  int x = 10;

This code creates a variable called “x” and sets its value to 10. First, the line starts by declaring the data type of the variable using the keyword “int”, which stands for ‘integer’ — a number without a decimal point. After that, the variable is given the name “x”, and the equals sign signifies that we are setting the value of the variable. Finally, the value of the variable is set to 10.
