#C #data #types

char a = 'C'; // single character %c

float c = 3.141592; // 4 bytes (32 bits of precision) 6 - 7 digits %f
double d = 3.141592653589793; // 8 bytes (64 bits of precision) 15 - 16 digits %lf

bool e = true; // 1 byte (true or false) %d

char f = 120; // 1 byte (-128 to +127) %d or %c
unsigned char g = 255; // 1 byte (0 to +255) %d or %c
