Can i give an integer value to a 'char' variable in C language? Ex- char a = 4;

Answer 1

As a matter of fact, you can, but:
The char variable will store the corresponding character of the ASCII integer value. The integer value itself will not be stored. E.g.

char a = 59;
cout << a;

// outputs ;

Answer 2

yes you can assign integer value to char variable but on printing that variable you will be able to see ascii code corresponding to the value assigned to the variable
