how to know a type of a numbe in c

Checking the Type of a Number in C

To check the type of a number in C, you can use the sizeof operator and the printf function to display the size of the variable in bytes. Here are the steps:

1. Declare the Variable: Declare a variable of the type you want to check.

2. Use the sizeof Operator: Use the sizeof operator to determine the size of the variable in bytes.

3. Display the Size: Use the printf function to display the size of the variable.

Here's an example of how you can do this:

#include <stdio.h>

int main() {
    int num;
    float decimalNum;

    printf("Size of int: %d bytes\n", sizeof(num));
    printf("Size of float: %d bytes\n", sizeof(decimalNum));

    return 0;
}

In this example, the sizeof operator is used to determine the size of the int and float variables, and the printf function is used to display the size in bytes.
