- Question
What will be the output of the program in Turb C (under DOS)?
#include<stdio.h> int main() { int arr[5], i=0; while(i<5) arr[i]=++i; for(i=0; i<5; i++) printf("%d, ", arr[i]); return 0; }
Options- A. 1, 2, 3, 4, 5,
- B. Garbage value, 1, 2, 3, 4,
- C. 0, 1, 2, 3, 4,
- D. 2, 3, 4, 5, 6,
- Correct Answer
- Garbage value, 1, 2, 3, 4,
ExplanationSince C is a compiler dependent language, it may give different outputs at different platforms. We have given the TurboC Compiler (Windows) output.Please try the above programs in Windows (Turbo-C Compiler) and Linux (GCC Compiler), you will understand the difference better.
