Consider inspecting the expression. The 'strcmp' function returns 0 if corresponding strings are equal. Function execution could be deferred. If an expression is not given on a return statement in a function declared with a non- void return type, the compiler issues a warning message. The 'bar2.h' header will be excluded from compilation. In a main function, the return statement and expression are optional. Check lines: N1, N2. Explicit conversion from 32-bit integer type to pointer type. V2575. This leads to the variable binding to a temporary object instead of a range element. The '+' operation is executed. V6103. Implicit type conversion of return value from memsize type to 32-bit type. The 'switch' statement should have 'default' as the last label. Function body contains the 'X' label that is not used by any 'goto' statements.
