Blind Coding Round 1

C programming : Match the following:

a. calloc( ) ------- i. Frees previouslyallocated space.

b. free( ) ----------- ii. Modifiespreviouslyallocated space.

c. malloc( ) ------- iii. Allocates spacefor array.

d. realloc( ) ------- iv. Allocatesrequested size ofspace.

• a-iii, b-i, c –iv, d -ii

• a-iii, b-ii, c –i, d -iv

• a-iii, b-iv, c –i, d -ii

• a-iv, b-ii, c –iii, d -i

C programming:The given expression P– = Q+1 is same as

• P = P – Q – 1

• P = P – Q + 1

• P = –P + Q + 1

• None of the above

Trace the output.

int main()

{

char *str="careerride";

printf("%d",printf("%s",str));

return 0;

}

• 10careerride

• careerride

• careerride10

• Compile time error.

Trace the output.

void main()

{

int x=-5,y,num=5;

y=x%-4;

y=(y?0:num*num);

printf("%d",y);

}

• 25

• 0

• -25

• None of the above.

C programming : Trace the output

While(“%d” , printf(“abc”))

{

Printf(“de”);

}

• abdededede…………………

• Compile error.

• abcdeabcdeabcde……………

• None of the above.

Which of the following allows the programmer to destroy an object x? (Java)

• x.delete()

• x.finalize()

• Runtime.getRuntime().gc()

• Only the garbage collection system can destroy an object.

Java Virtual Machine is platform independent?

• True

• False

In which package do we have the gc() method?

• java.lang package

• java.util package

• java.awt package

• java.io package

Point out the correct statements are correct about the program below?

#include int main() {    

char ch;    

while(x=0;x<=255;x++)        

printf("ASCII value of %d character %c\n", x, x);    

return 0;

}

• The code generates an infinite loop

• The code prints all ASCII values and its characters

• .Error: x undeclared identifier

• Error: while statement missing

If a function contains two return statements successively, the compiler will generate warnings. Yes/No?

• Yes

• No
