Infosys Pseudo Code Questions

Infosys Pseudo-code Questions with Answers 2022 are available below on this page. Pseudo Code is a normal representation of algorithm code in C, C++ or any other language. In Pseudo Code round there will be a total of 5 questions that we need to answer within 10 minutes. The Difficulty level of the paper goes from Moderate to High. Pseudo-Code are not the machine-readable codes it is just as same as algorithm written in coding format. For more detailed information on Infosys Examination, You can visit our Infosys Dashboard.

1. What is the output?

#include<stdio.h>
int main()
{
    for (int x = 10; x >= 0; x--) {
        int z = x & (x >> 1);
        if (z)
            printf("%d ", x);
     }
    
}

Here, in the given code, >> is the bitwise right shift operator and x>>y => x/(2^y) and & is the bitwise and operator and gives 1 only if both bits are same. Now, for x = 10, (10>=0) z = 10 & (10>>1) => z = 10 & 5 => z=10. Similarly for x= 9, 8, 5, 4, 2, 1 and 0 , z will be zero and for x=7, z will be 3 , for x= 6, z will be 2 and for x=3, z will be 1 for x=7, 6, and 3 z is non zero so the will get printed on the output screen. Hence, we get output as 7 6 3

Good Job! Did you know? : With $8.5 billion in their kitty, Wipro is the 4th largest Indian IT company in terms of revenue.

Oops!

2. What is the output?

#include<stdio.h>
int main()
{
    int a = 100;
    printf("%0 %x", a);
}

None

In this question %0 will cancel out the a, while %x will get printed
but,
if we only write printf("%x"); without passing any parameter for x,
it will show an error.

3. What is the output?

#include<stdio.h>
int main() 
{
    typedef int num;
    num bunk = 0.00;    
    printf("%d", bunk);
    return 0;
    
}

Zero

34.37%

0.0

25.33%

garbage value

22.21%

Logical Error

18.08%

Integer part of 0.00 is equal to 0.
Hence only zero will be printed with printf("%d", bunk), when 0.00 is passed, because %d stands for integer.

Good Job! Did you know? : With $8.5 billion in their kitty, Wipro is the 4th largest Indian IT company in terms of revenue.

Oops!

4. What is the output?

#include<stdio.h>
int main(){
    float x = 0.0;
    long int y = 10;
    printf("%d", sizeof(y) == sizeof(x+y));
    return 0;
}

23.03%

zero

52.67%

12.79%

11.51%

sizeof(x), that is float, is 4
sizeof(y), that is long int, is 8
sizeof(x+y) that also comes out to be float will have size = 4

here it is asking sizeof(y) == sizeof(x+y)
i.e 8 == 4
"==" operator gives result in either 0 or 1
so answer is zero.

5. What is the output?

#include<stdio.h>
int main()
{
    int any = ' ' * 10;
    printf("%d", any);
    return 0;
}

Ascii value of space (' ') is 32 and 32 * 10 is 320

6. What will be the output of the following pseudocode:

#include<stdio.h>
int main()
{
int go = 5.0, num = 1*10;
do 
{
num /= go;
} while(go--);
printf ("%d\n", num);
return 0;
}

Floating Point Exception

None

In C when you divide the integer with a float without the type casting it gives "Floating Point Exception" error

What will be the output of following pseudo code

#include<stdio.h>
int main(){
    float x = 0.0;
    long int y = 10;
    printf("%d", sizeof(x) == sizeof(x+y));
    return 0;
}

20.98%

zero

73.13%

4.23%

1.66%

sizeof(x) that is float is 4
sizeof(y) that is long int is 8
sizeof(x+y) that also comes out to be float will have size = 4

here it is asking sizeof(x) == sizeof(x+y)
i.e 4 == 4
"==" operator gives result in either 0 or 1
so answer is 1.

8. What will be the output of the following pseudocode:

#include <stdio.h>

int main()

{

int num = 987;

int rem;

while(num!=0)

{

rem = num % 4;

num = num / 10;

}

printf("%d",rem);

}

zero

24.67%

36.15%

11.4%

27.78%

Iteration 1 : rem = 3(987 % 4), num = 98
Iteration 2 : rem = 2(98 % 4), num = 9
Iteration 3 : rem = 1(9 % 4), num = 0

9. what will be the output of the following Pseudo Code.

#include<stdio.h>
int main()
{
float i;
i = 1;
printf("%d",i);
return 0;
}

29.61%

Garbage Value

20.8%

1.000000

34.93%

Error

14.66%

If float variable is declared as an integer type
then, it will always give garbage value.

10. What will be the output of the following pseudocode:

public class Main
{
     public static void main(String[] args)
     {
          String names[] = new String[5];
          for(int x=0; x<args.length; x++)
          names[x] = args[x];
          System.out.println(names[2]);
     }
}

Names

14.67%

Null

37.27%

Compilation fails

20.49%

An exception throws at runtime

27.57%

value of args.length is 0
So, the loop will not run either of the time
Hence, null will be printed.
