Question

Entering a char value into an int variable causes serious errors, called input failure.

A. True.
B. False.

Answer 1

It is true that entering a char value into an int variable can cause input failure, as variables are type-specific and expect data of a particular type. Misalignment of data types can result in errors or unexpected behavior.

Step-by-step explanation:

Entering a char value into an int variable can indeed lead to issues, often described as input failure. This is true because variables in programming are type-specific, meaning that an int variable is meant to store integer values only. When a char value is input into an int variable, the system may not correctly interpret this data, causing an error or a situation where the program does not behave as expected.

The exact behavior can vary depending on the language and the circumstances. For instance, some programming environments might automatically convert the char to its ASCII equivalent integer value, while others may throw a compilation or runtime error. In any case, always ensure that the data type of the input matches the expected data type of the variable to prevent such variable causes of error.
