for (i=0;i<20;i++)
printf(“\n%d”,x[i]);
getch();
}

int x[50],i;
clrscr();
for (i=0;i<=50;i++)
{
X[i]=i;
Printf(“\n %d”,x[i]);
}
getch();
}
Q-4)what is the output of following program?

QUIZ-6 OF C PROGRAMMING LANGUAGE
Answer with explanation
1)Errors:
constant expression required in function main.size of array not known in function main solution:We cannot initialize an array using a variable i.e,the size of array should be known at the compile time.Declare the array as:int arr[5];
2)Error:Program executes but the value displayed for remaining array indices are garbage values.
Solution:There is no bound checking in c.Loop should iterate from 0 to 4 only.
3)Error:
program compiles successfully but may give undesired values in the output
Solution:the valid indices are 0 to 49.
4) OUTPUT: 10
5)OUTPUT: T
ill the stack does not overflow.
6)output: 1
Explanation:
x gives number of arguments given while invoking the command.
7)D
Explanation
short is used as an alternative of short int.
8)B
Explanation
Compilation is the process of translating high level language statements into equivalent machine code, which is object code.
9)B
Explanation
*s=’N’, changes the character at base address to ‘N’.
10)C
Explanation
Length of the string is count of character upto ‘\0’. sizeof – reports the size of the array.
