Qbasic is a program that allows the user to enter the values at runtime (when the program is executed).
1. THE INPUT STATEMENT- The INPUT statement allows the user to assign values to variables during program execution. The syntex for the INPUT statements written as:
INPUT <prompt>; variable
The prompt informs the user about what he is expected to enter. Example: INPUT "Please enter your age"; a In the above statement if the user enters the value 8, it is assigned to the variable 'a'.
When the input statement is executed, the computer does four things:
1. It stops execution of the program.
2. It prints the prompt message along with a question mark.
3. It waits for the user to enter some data.
4. It assigns the data entered to the variables named in the INPUT statement.
