Declaring a Variable of Type "long" in C programming

How to Declare a long Variable in C

In C programming, the long data type is used when you need a variable capable of holding larger integer values than the standard int. The long data type is typically 4 or 8 bytes in size, depending on the system architecture.

Declaring a long Variable

To declare a variable of type long in C, you can use the following syntax:

long variableName;

Here, variableName is the name you choose for the variable. For example:

long myNumber;

This statement declares a variable named myNumber of type long.

Example: Declaring and Initializing a long Variable

In most cases, you will declare and initialize a long variable at the same time. Here’s an example:

#include <stdio.h>

int main() {
    long myNumber = 1234567890L;

    printf("The value of myNumber is: %ld\n", myNumber);

    return 0;
}

In this example:

• myNumber is declared as a long and initialized with the value 1234567890L.
• The L suffix indicates that the literal value is of type long.

Note: When printing a long variable using printf, use the format specifier %ld for signed long integers.
