how to take input in C

To take input in C, you can use the scanf function. Here's how you can do it:

1. Include the necessary header file at the beginning of your program: c #include <stdio.h>

2. Declare variables to store the input: c int num; char name[20];

3. Use the scanf function to read input from the user: ```c printf("Enter a number: "); scanf("%d", &num);

printf("Enter your name: "); scanf("%s", name); ```

In the above code, %d is the format specifier for an integer, and %s is the format specifier for a string. The & operator is used to get the address of the variable where the input should be stored.

1. You can now use the input in your program as needed: c printf("You entered: %d\n", num); printf("Your name is: %s\n", name);

The printf function is used to display the input back to the user.

That's it! You have successfully taken input in C using the scanf function. Remember to include error handling and validation for user input to ensure your program behaves as expected.
