What is a memory leak in C++?When the program uses too much memoryWhen memory is not allocated properlyWhen dynamically allocated memory is not freedWhen the program tries to access restricted memory

n C++, syntax errors occur when the code violates the rules of the language, such as missing semicolons or incorrect variable declarations. Logic errors happen when the coder mistakenly swaps the operands in a comparison operation, leading to incorrect conditional behavior in the program, like erroneously accepting invalid inputs in a validation check. Runtime errors occur during program execution, such as accessing an invalid memory location or dividing by zero. To identify and debug these errors, I utilize techniques like code review, testing, and debugging tools like breakpoints and print statements. Preventing errors involves employing defensive programming practices like input validation, boundary checks, and writing modular, well-structured code. Additionally, using static code analysis tools and following established coding standards can catch potential issues early in development. By practicing defensive programming and adhering to best practices, I strive to minimize errors and ensure the reliability and stability of my C++ code.

What happens if we run the following code?12345678#include <iostream>int main() { int* ptr = new int; ptr = new int; delete ptr; return 0;}Marks : 1Negative Marks : 0Answer hereThe code will not compile due to a syntax error.The code will compile and execute without any issues.The code will compile but result in a memory leak.The code will compile but result in an allocation failure.
