This program iswrongbecause we have two case ‘A’ here which is wrong as we cannot have duplicate case values. #include<stdio.h>intmain(){charch='B';switch(ch){case'A':printf("CaseA");break;case'A':printf("CaseA");break;case'B':printf("CaseB");break;case'C':printf("CaseC ...

The values of expression and each constant-expression must have an integral type. A constant-expression must have an unambiguous constant integral value at compile time. Control passes to the case statement whose constant-expression value matches the value of expression. The switch statement can inclu...

Microsoft C does not limit the number of case values in aswitchstatement. The number is limited only by the available memory. ANSI C requires at least 257 case labels be allowed in aswitchstatement. The default for Microsoft C is that the Microsoft extensions are enabled. Use the /Za compi...
