What is Semantic errors in c?

Answer 1

A semantic error is a logic error. That is, the code may compile and run, but does not perform as you intended.

Some semantic errors can be picked up by the compiler, often shown as warning, such as:

if (x = 5) // warning: did you mean x == 5?

Others are simply impossible for the compiler to spot:

int x, y, z;

// ...

++z; // add 1 to x

In the above code, we meant to increment x, but incremented z instead. The compiler won't notice the error so this will inevitably lead to a runtime error.

Answer 2

when we declare an array then we declare it as follows:

data type array[size]

here ,

1)The size should be assign a value

2) That value should be an integer

If we give the value as float then the (1) criteria is satisfied but the (2) creteria is not yet satisfied, thus it creates an error.

Such type of error are refered as SEMANTIC ERRORS.

Answer 3

semantic errors are logical errors due to illogical statements in program.

due to this program may terminates immediately or Enter into infintie loop
