long long int
We can even apply the long modifier to long int to further increase the size of the data type. The long long int is often used when the range of values exceeds the long data type.
- The size of the long long int is 8 bytes.
- It can represent integer values from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.
- The format specifier for the long long data type is %lld.
- The long int literals can be represented by a numeric value followed by “LL” or “ll” as the suffix.
Syntax of long long int
long long int var;
As with the long int, we can also declare long long int by only using long long keywords.
long long var;
Example of long long int
C
// C program to illustrate the long long int #include <stdio.h> int main() { // declaring long long int variables using both ways long long int var1; long long var2; // printing the size of long long it printf("Size of var1: %d\nSizeof var2: %d", sizeof(var1), sizeof(var2)); return 0; } |
Output
Size of var1: 8 Sizeof var2: 8
C Long
In C, the long keyword is a datatype modifier that can be applied to the basic datatypes to increase the range and size of values their variables can store. For example, a long int variable can store integer values that range from -2,147,483,648 to 2,147,483,647 which is significantly greater as compared to the normal int data type, which can store integer values that range from -32,768 to 32,767 in the 16-bit compiler.
