converting char to unsigned int

[thepersonof]

Thankyou ... converted to an unsigned char and it works great

[Wim Engberts]

union { char c[sizeof (int)]; int n; } Convert; char c = 250; Convert.n = 0; Convert.c[0] = c; Then, in Convert.n you will get the proper value. Good luck! William

int a = int(c)

A cast is actually not necessary. You could accomplish the same with:

int a = c;

because a char gets internally promoted to an int during such operations. A char can hold values in the range -128 to 127, whereas an unsigned char can hold values in the range 0 to 255.

Hi there. As the other replies have stated, you need to use the unsigned char for values above 127. To perform explicit conversions in C++, you should use the static_cast instead of the old C-Style casts. unsigned char c = 250; int a = static_cast<int>(c); Cheers

For integral types, this is not necessary.

Quite agree. It is not necessary, the unsigned char will be cast correctly without it. I recommended it though, as it does explicity show the intentions of the developer.
