c unsigned char array initialization
char c = 200; unsigned char *puc = (unsigned char *)&c; signed char *psc = (signed char *)&c; printf("unsigned=%d signed=%d\\n", *puc, *psc); // data that stores in the variable c can be printed as both signed and unsigned Guided by the type of variable (signed or unsigned) a compiler uses the appropriate operations for
How do I initialize a char array in C?
1To initialize a char array in C, you can use either of the following ways:2Initializing the array with a string literal:3In this method, the array is initialized with the string "Hello".
4) Initializing the array element by element:5In this method, each element of the array is initialized explicitly.
How do you initialize an unsigned char array?
unsigned char ch = 'a'; Initializing an unsigned char: Here we try to insert a char in the unsigned char variable with the help of ASCII value.
So the ASCII value 97 will be converted to a character value, i.e. 'a' and it will be inserted in unsigned char.6 août 2020
