Ramco Systems Placement Question Paper

1. How many butes does an array A(1:8,-2:2,1:5) require for storage if each element of the array is 24 bits long.
200 480 600 800 none

2. begin
i:=0;
j:=0; | block d
loop:
if(i != 0)
i := i-1;
else
i := i+1;

i := i+1; | block a
j := j+1; | block b
if (j < = 25)
goto loop;

end | block c
a) What is the value of i at [c]
2 ?
b) How many times is the goto executed
25 ?
c) How many times is the loop executed if i is initialized to 1
in [d] 26
d) How many times is the loop entered if the block [b] is changed
to j=j+1 ?
e) What is the value of i at [c] interchanging blocks [a] and [b] ?
2 ?

2. F occurs only if B occurs
3. D occurs if B or C occurs
4. E occurs if only c occurs
5. J occurs only if E or F occurs
6. H occurs if E occurs

1) Find the output for the following C program
main()
{
char *p1="Name";
char *p2;
p2=(char *)malloc(20);
while(*p2++=*p1++);
printf("%sn",p2);
}
Ans. An empty string

2) Find the output for the following C program
main()
{
int x=20,y=35;
x = y++ + x++;
y = ++y + ++x;
printf("%d %dn",x,y);
}
Ans. 57 94
3) Find the output for the following C program

main()
{
int x=5;
printf("%d %d %dn",x,x<<2,x>>2);
}
Ans. 5 20 1

4) Find the output for the following C program
#define swap1(a,b) a=a+b;b=a-b;a=a-b;
main()
{
int x=5,y=10;
swap1(x,y);
printf("%d %dn",x,y);
swap2(x,y);
printf("%d %dn",x,y);
}
int swap2(int a,int b)
{
int temp;
temp=a;
b=a;
a=temp;
return;
}
Ans. 10 5
5) Find the output for the following C program
main()
{
char *ptr = “Ramco Systems";
(*ptr)++;
printf("%sn",ptr);
ptr++;
printf("%sn",ptr);
}

Ans. Samco Systems
6) Find the output for the following C program

#include
main()
{
char s1[]="Ramco";
char s2[]="Systems";
s1=s2;
printf("%s",s1);
}
Ans. Compilation error giving it cannot be an modifiable ‘lvalue’
7) Find the output for the following C program
#include
main()
{
char *p1;
char *p2;
p1=(char *) malloc(25);
p2=(char *) malloc(25);
strcpy(p1,"Ramco");
strcpy(p2,"Systems");
strcat(p1,p2);
printf("%s",p1);
}Ans. RamcoSystems
8) Find the output for the following C program given that
[1]. The following variable is available in file1.c
static int average_float;
Ans. All the functions in the file1.c can access the variable
9) Find the output for the following C program
# define TRUE 0
some code
while(TRUE)
{
some code
}
Ans. This won’t go into the loop as TRUE is defined as 0

main()
{
int x=10;
x++;
change_value(x);
x++;
Modify_value();
printf("First output: %dn",x);
