Technical Round 1

  1. Tell me something about yourself?
  2. Explain your projects?
  3. Find prime numbers from 0 to a number enter by user.
  4. Sort a char array in alphabetical order using bubble sort.

int main (void)
char string[128], temp;
int n, i, j;printf(“\nEnter string: “);
n = strlen(string);

for (i=0; i<n-1; i++)
for (j=i+1; j<n; j++) { int s = tolower(string[i]) – tolower(string[j]); if ( s == 0 ) { // letters are the same… now watch out for case s = string[i] – string[j]; } if (s > 0)
temp = string[i];
string[i] = string[j];
string[j] = temp;
printf(“\n%s”, string);
return 0;

  3. Write a program to do a+b and a-b using different threads.
  4. Write a program to do a+b and a-b using different process (Parent and child process).
  5. Write a SQL query to find emp_id,emp_name,emp_manager_name from following table:
    (employee is table name)

select emp_id,emp_name,x.emp_name from employee inner join employee as x where emp_id=x.emp_id;
