The main difference is that int values are treated as being integers whereas char values are treated as being character codes. Thus if you output a char with value 65 you will get the symbol 'A', but if you output an int with the value 65 you will get the value 65 instead. In order to output the symbol 'A' you would have to cast the int to a char.

How do you create functions with multiple parameters in C plus plus?

Integers need how many bits to stored in C plus plus?
It depends on the type of integer (such as long, short, int and char) and the specific implementation of C++. The only guarantee is that a char must occupy one byte (sizeof(char)==1). An int is typically 32-bits (4 bytes), but only sizeof(int) can tell you for sure.

How do you convert a char to and int in c plus plus but keep the value of the char so if the char was 3 the int would also be 3?
Formally, you cannot do this. A char containing a character value has a different bit configuration than an int. Attempting to convert between the two is non-portable. However, in the ASCII character set, the character '0' has the value 48, or 0x30. If you subtract 48 from the char you will get the int value, but only if the char was one of the digits '0' through '9'. It is better to use the library routines to convert, such as atoi and sscanf, because they will give you predictable, portable results.

Yes, for example: #include <stdio.h> int main ( int argc, char **argv) {puts ("Hello, world"); return 0; }
