What is the actual size of INT in the C language, 2 or 4 bytes?
The actual size to int is determined by the compiler as the program runs. But theoretically the size is 2 bytes. You can increase the size by adding keyword long infront of it to make the size 4 bytes. Eg int a; // 2 bytes Long int b; // 4 bytes
