RE: [Dev-C++] Unsigned and signed

[Ioannis V. <no...@ya...>]

signed integer variables can store both positive and negative variables,
unsigned only positive.=20

e.g.
int x;
signed int x; // They are both the same

unsigned int x;

long y;
signed long y; // They are both the same

unsigned long y;


In the case of int the "int" can be avoided:

int x;
signed x; // They are both the same

unsigned x;


Also normally we do not use signed but only unsigned when we need so:

int x; // signed
long y; //signed

unsigned z; // unsigned int
unsigned long y;
unsigned char c;

But a char it can be signed or unsigned. It depends from the system.

E.g. char c; // it can be signed or unsigned

signed char c; // signed
unsigned char c; // unsigned
