What type of error manifests only when a program is executed rather than during compilation?

Execution errors refer to issues that occur while a program is running, rather than during the compilation process. This type of error only becomes apparent once the code is executed. During execution, the program may encounter various problems, such as attempting to divide by zero, accessing invalid memory, or running out of available resources, which do not show up until the program is actively in operation.

While syntax errors prevent the code from being compiled successfully due to mistakes in the code structure, and compilation errors arise during the translation of the code into machine language, execution errors specifically highlight problems that occur as a result of the actions specified within the program during its execution phase. Runtime errors, which are often encountered during the execution of programs, can also be considered a subset of execution errors related to unforeseen conditions that occur while the program is running.
