Answer with exaplaination:
1)B
Explaination
*s=’N’, changes the character at base address to ‘N’.
2)CExplaination
Explaination
2 4 6, at while first compared and later incremented and in printf printed first and incremented later.
3)D
Explaination
-2, the one’s compliment of 1 is 1110 (binary) which is equivalent to two’s compliment of 2, ie -2
4)B
Explaination
‘cc’ full form is C Compiler and is the compiler for UNIX. gcc is GNU C compiler for linux. Borland and vc++ (Microsoft visual c++) for windows.
5)B
Explaination
Strstr() finds the first occurrence of a substring in another string.
6)C
Explaination
If while(j <= 300),then whatever the size short int value, the while loop condition will execute until j value becomes 300.
#include<stdio.h> int main (){ int j = 1; while(j <= 300) { printf(“%c %d\n”, j, j); j++; } return 0;}
7)C
Explaination
B is a programming language developed at Bell Labs in 1969. It is derived from BCPL (Basic Combined Programming Language). It is designed by Ken Thompson with Dennis Ritchie.
8)B
Explaination
Explanation: The integral and precession value varies depending upon the number of bytes designated for a particular data type.
9)C
Explaination
0, data bits are lost for the above shift operation hence the value is 0.
10)C
Explaination
0 8, enums gives the sequence starting with 0. If assigned with a value the sequence continues from the assigned value.
