Answers:

The switch statement is better than multiple if statements when there are more than two alternatives to be selected whether the case value matches to the variable of either character or integer type.

IN CASE OF A SWITCH STATEMENT,
THE CURSOR STRAIGHT AWAY JUMPS TO THE REQUIRED CASE AND OVERLOOKS OTHER STATEMENTS. AS SOON AS THE EXECUTION IS OVER IT MOVES OUT OF THE OTHER IRREVALENT STEPS PERTAINING TO THE REQUIRED CONDITION
BY THE HELP OF "break" STATEMENT,THEREBY REDUCING THE TIME COMPLEXITY OF THE PROGRAM.
WHEREAS "if" STAEMENT IS USEFUL WHEN THE NUMBER OF CONDITIONS TO BE CHECKED IS LESS.

All the programs are tested under Turbo C/C++ compilers.
It is assumed that,
?? Programs run under DOS environment,
?? The underlying machine is an x86 system,
?? Program is compiled using Turbo C/C++ compiler.
The program output may depend on the information based on this assumptions (for example sizeof(int) == 2 may be assumed).

Predict the output or error(s) for the following:

i) void main()
{
int const * p=5;
printf("%d",++(*p));
}
