Understanding the C Program with Switch Statement
In C programming, the `switch` statement is used for multi-way branching. It evaluates an expression and executes the corresponding case block. However, if there are syntax errors or improper use of the statement, it can lead to a compiler error.
Common Reasons for Compiler Errors in Switch Statements
- Missing Break Statement: If a `break` statement is omitted, the control will "fall through" to subsequent cases.
- Invalid Case Labels: Each case must be a constant expression. Using variables or non-integer values will result in an error.
- Incorrect Syntax: The switch statement must be correctly structured; missing braces or parentheses can lead to errors.
Example of a Compiler Error
c
#include
int main() {
int x = 1;
switch (x) {
case 1:
printf("RABBIT");
case 2:
printf("ZERO RABBIT");
// Missing break statements here
}
return 0;
}
In the above example, if there are no proper `break` statements, the program will compile but produce unintended results. However, if there are missing braces or incorrect syntax, it will lead to a compiler error.
Conclusion
The provided options suggest that the correct answer is a compiler error (`D`). This typically arises from improper syntax or misuse of the `switch` statement. Always ensure that your code adheres to C syntax rules to avoid such errors.
