Explanation / Answer

Q23-
The result variable will be assigned result=7 because if(a==(a+1)) will be false so result=5 will not execute
then reult will be assigned 6 after the if condition and at the end result will be 7 so at the end result=7.

Q24-if result variable is of type integer then result will be 98 and if it is of type char then result=b;
Q25-result will be false as both the condition cannot be true and we have && operator so one of the condition will be false
so the result will be false.
Q26-result will be 14 as it is static casted to integer type.
Q27- x=x+y;
Q28- The three peices of information provided by function header is
1- function return type
2-function name
3-function parameterlist

Q29-Yes 2E5A and 2e5a both are equivalent as hexadecimal is case insensitive.

Q30-Function signature is the another name for function declaration.
