SAP Placement Papers - Interview Questions:
1. If int is 2 bytes wide.What will be the output of the program?
#include
void fun(char**);
int main()
{
char *argv[] = {"ab", "cd", "ef", "gh"};
fun(argv);
return 0;
}
void fun(char **p)
{
char *t;
t = (p+= sizeof(int))[-1];
printf("%s\n", t);
}
A.ab B.cd C.ef D.gh
Answer: B
2. What will be the output of the program if the array begins at 65486 and each integer occupies 2 bytes?
int main()
{
int arr[] = {12, 14, 15, 23, 45};
printf("%u, %u\n", arr+1, &arr+1);
return 0;
}
A.12, 65490 B.14, 65492 C.65488, 65496 D.64490, 65498
Answer: C
Explanation:
Here, the base address(also the address of first element) of the array is 65486. => Here, arr is reference to arr has type "pointer to int". Therefore, arr+1 is pointing to second element of the array arr memory location. Hence 65486 + 2 bytes = 65488 => Then, &arr is "pointer to array of 5 ints". Therefore, &arr+1 denotes "5 ints * 2 bytes * 1 = 10 bytes". Hence, begining address 65486 + 10 = 65496. So, &arr+1 = 65496. Hence the output of the program is 65488, 65496.
3. Recursive functions are executed in a
A.last in first out order B.first in First out order C.Are maintained in a stack D.none of the above
Answer: A
4. What will be the output of the program?
#include
int main()
{
int i=3, j=4, k, l;

return 0;
}
int addmult(int ii, int jj);
{
int kk, ll;
kk = ii + jj;
ll = ii * jj;
return (kk, ll);
}
A.Function addmult()return 7 and 12 B.No output C.Error: Compile error D.None of above
Answer: C
Explanation:
There is an error in this statement int addmult(int ii, int jj);. We have to remove the semi-colon, because it was an definition of the function addmult()

return 0;
}
A.25 B.11 C.Error D.Garbage value
Answer: B
Explanation:
11 Answer: 11 Explanation: a = SQR(b+2); becomes, => a = b+2 * b+2; Here SQR(x) is replaced by macro to x*x . => a = 3+2 * 3+2; => a = 3 + 6 + 2; => a = 11;
14. What will be the output of the program if value 25 given to scanf()?
#include

}
A.1 B.2 C.5 D.25
Answer: A
Explanation:
The scanf function returns the number of input is given. printf("%d\n", scanf("%d", &i)); The scanf function returns the value 1(one). Therefore, the output of the program is '1'.
