When you enter a text and press enter, then program proceeds and reads the input and displays it as follows − $./a.out Enter a value: seven 7 You entered: seven 7 Here, it should be noted that scanf expects input in the same format as you provided%s and%d, which means you have to provide valid inputs like 'string integer'. Write a C, C program which accepts an input name and print it. This is a basic programming question in which you have to take an input from a user and print it. C, C Programming Interview Questions Program to add two numbers Basic programs for practice C Program that Accept an Input Name and Print it. Question: Using Dev C Program, Create A C Program That Implements A Menu Of The Following: When The User Input 1, For Example, It Will Ask The User To Choose The Following Sub-functions: The Program Should Be In #include Create A Program That Lets The User Choose A Function (Temperature Conversion, Force Conversion, Si-imperial Conversion) From The Menu.

Algorithm to Find Smallest of three Numbers
1. Declare three variable a ,b, c.
2. Compare a with b and c. If a is smaller than b and c than a is smallest among three numbers.
3. Compare b with a and c. if b is smaller than a and c than b is smallest among three numbers.
4. Else c is smallest among three numbers.

User Input C++ Visual Studio
Get User Input
You have already learned that Console.WriteLine() is used to output (print) values. Now we will use Console.ReadLine() to get user input.
In the following example, the user can input his or hers username, which is stored in the variable userName. Then we print the value of userName:
User Input and Numbers
The Console.ReadLine() method returns a string. Therefore, you cannot get information from another data type, such as int. The following program will cause an error:
Example
The error message will be something like this:
Like the error message says, you cannot implicitly convert type 'string' to 'int'.
Luckily, for you, you just learned from the previous chapter (Type Casting), that you can convert any type explicitly, by using one of the Convert.To methods:
Example
Note: If you enter wrong input (e.g. text in a numerical input), you will get an exception/error message (like System.FormatException: 'Input string was not in a correct format.').
