How does the program's flow change if one of the variable assignments is mistyped as a comparison?

When a variable assignment is mistyped as a comparison, it can lead to an unintended behavior during the program's execution. The correct interpretation of this situation often hinges on the specific programming language being used. In many programming languages, an assignment (using an equals sign) is distinct from a comparison (typically using double equals or other comparison operators).

If what was intended to be an assignment is mistakenly written as a comparison, the outcome can drastically alter the program's logic. For example, in languages where a single equals sign (=) is for assignment and a double equals sign (==) is for comparison, a mistyped single equals sign instead of a double would yield an assignment operation rather than a condition check. Consequently, if the programming language does not recognize this as invalid syntax or a compile error, it often leads to logic errors rather than terminating the program due to a compile error.

In languages like C or C++, the code will compile even with such a mistake, meaning that the statement is syntactically correct but semantically incorrect for the intended logic. Thus, it does not cause the program to crash, but it leads to unexpected flow control and possibly incorrect results or outputs since the intended condition is not evaluated as expected.

Therefore, saying that
