- c++ - What does int mean - Stack Overflow
A C++ question, I know int* foo (void) foo will return a pointer to int type how about int foo (void) what does it return? Thank a lot!
- Is there a difference between int a and int a? - Stack Overflow
int a, b; Here, b is declared as an integer (not an integer reference) because, when used in a declaration, the (or *) is linked to the individual variable that it precedes, not to the type that it follows
- Difference between int32, int, int32_t, int8 and int8_t
Plain int is quite a bit different from the others Where int8_t and int32_t each have a specified size, int can be any size >= 16 bits At different times, both 16 bits and 32 bits have been reasonably common (and for a 64-bit implementation, it should probably be 64 bits)
- c# - What is the difference between “int” and “uint” “long” and . . .
I know about int and long (32-bit and 64-bit numbers), but what are uint and ulong?
- What range of values can integer types store in C++?
The minimum ranges you can rely on are: short int and int: -32,767 to 32,767 unsigned short int and unsigned int: 0 to 65,535 long int: -2,147,483,647 to 2,147,483,647 unsigned long int: 0 to 4,294,967,295 This means that no, long int cannot be relied upon to store any 10-digit number However, a larger type, long long int, was introduced to C in C99 and C++ in C++11 (this type is also often
- Is the size of C int 2 bytes or 4 bytes? - Stack Overflow
238 I know it's equal to sizeof(int) The size of an int is really compiler dependent Back in the day, when processors were 16 bit, an int was 2 bytes Nowadays, it's most often 4 bytes on a 32-bit as well as 64-bit systems Still, using sizeof(int) is the best way to get the size of an integer for the specific system the program is executed on
- c - What does -1 represent in the value range for unsigned int and . . .
Assuming as in your example that unsigned int has a value range of 0 to 4,294,967,295 the value -1 is converted by adding -1 + 4,294,967,296 = 4,294,967,295 Note that this conversion happens regardless of how negative numbers are represented on the given system It is the same for two's complment, ones' compliment, or sign-and-magnitude
- The real difference between int and unsigned int
The real reason that this can happen is that C is a weakly typed language But unsigned int and int are really different
