Find the odd one out related to Array concept

• Code optimization

• Fixed size

• Ease of sorting

• Random access

1. #include<stdio.h>  

2. int main(){      

3. int i=0;    

4. int marks[5]={20,30,40,50,60};

5. for(i=0;i<5;i++){      

6. printf("%d \n",marks[i]);    

7. }    

8. return 0;   }

9. FIND THE OUTPUT

• 20 60 30 50 40

• 60 50 40 30 20

• 30 40 50 60 20

• 20 30 40 50 60
