When I do c = c+5; it complains of "can't convert from int to char" while c += 5; works fine. Why?
@samhou88973 жыл бұрын
u should do c = (char) + (c + 5);
@smokinamby3 жыл бұрын
The first part, When you said "when I do" you're assigning the value of c+5 to a variable named c. The second part of your question, you're comparing 2 values, not assigning values. So the first one you assigned a value. The second one you're comparing a value. Assigning vs comparing. One operator will assign. Two operators will compare.
@smokinamby3 жыл бұрын
And the answer to your question is variable c is of type char. C+5 is an int (because it has a whole number). You cannot put an int into a char type variable. (Unless you cast it, which you'd only do if you're sure it's not gonna be losing any information). As I said in my last comment these are 2 completely different operations. The first operation you asked is ASSIGNING a value. The second operation you're COMPARING 2 values.
@smokinamby3 жыл бұрын
Your first statement you are 'saying' put this value in c. Your second statement you're 'saying' while c has this value, do this.
