Which of the following loop constructs will result in an infinite loop if the condition is never updated inside the loop body?

for (int i = 0; i < 10; i++) { if (i == 5) break; }

What happens if an array index goes out of bounds in C?

Compiler detects it and stops execution

What will happen if a function in C returns the address of a local variable?

The function executes successfully and returns the correct value

Compiler detects it and throws an error

The returned address always points to 0

What will be printed when the following code is executed? char str[ ] = "Programming"; printf("%s", str + sizeof(char) * 2);

The first two characters are omitted and the rest are printed.

Only the first two characters are printed.

Find the error in the following program: #include <stdio.h> int sum(int a, int b) { if (a + b > 10) return; return a + b; } int main() { int result = sum(5, 6); printf("%d", result); return 0; }

Undefined behavior due to missing return statement in sum()

Compilation error due to missing return type in sum()

What will be the output of the following C program? #include <stdio.h> int main() { int i = 1; while (i <= 5) { if (i % 2 == 0) continue; printf("%d ", i); i++; } return 0; }

The program enters an infinite loop due to a missing increment.

The program prints only odd numbers between 1 and 5.

The program prints all numbers from 1 to 5.

The program fails to compile due to incorrect loop syntax.

Spot the error in this code snippet: #include <stdio.h> int main() { const int age; age = 30; printf("%d", age); return 0; }

Syntax error in printf statement

How does a compiler differ from an interpreter?

A compiler translates the entire program at once, while an interpreter translates it line by line

A compiler executes code, while an interpreter does not

A compiler debugs code, while an interpreter does not

A compiler is used only in C programming, while an interpreter is not
