char: For characters. Size 1 byte.

 

char ch = 'A';

int: For integers. Size 2 bytes.

 

int num = 100;

float: For single precision floating point. Size 4 bytes.

 

float num = 123.78987;

double: For double precision floating point. Size 8 bytes.

 

double num = 10098.98899;

bool: For booleans, true or false.

 

bool b = true;

wchar_t: Wide Character. This should be avoided because its size is implementation defined and not reliable.
