This blog explains about QANTLER TECHNOLOGIES – Fresher Interview Questions with Answers – Session – 1 . They are explained clearly below :
Some of the frequently asked questions are :
____________________________________________________________________
1. Write a program to find the addition of digits ?
Addition of digits
// A Simple C++ program to compute sum of digits in numbers from 1 to n
#include<bits/stdc++.h>
using namespace std;
int sumOfDigits(int );
// Returns sum of all digits in numbers from 1 to n
int sumOfDigitsFrom1ToN(int n)
{
int result = 0; // initialize result
// One by one compute sum of digits in every number from
// 1 to n
for (int x = 1; x <= n; x++)
result += sumOfDigits(x);
return result;
}
// A utility function to compute sum of digits in a
// given number x
int sumOfDigits(int x)
{
int sum = 0;
while (x != 0)
{
sum += x %10;
x = x /10;
}
return sum;
}
// Driver Program
int main()
{
int n = 328;
cout << “Sum of digits in numbers from 1 to ” << n << ” is “
<< sumOfDigitsFrom1ToN(n);
return 0;
}

2. Write a program to find the addition of even digits ?
Addition of even digits
// C++ implementation to find sum of
// first n even numbers
#include <bits/stdc++.h>
using namespace std;
// function to find sum of
// first n even numbers
int evenSum(int n)
{
int curr = 2, sum = 0;
// sum of first n even numbers
for (int i = 1; i <= n; i++) {
sum += curr;
// next even number
curr += 2;
}
// required sum
return sum;
}
// Driver program to test above
int main()
{
int n = 20;
cout << “Sum of first ” << n
<< ” Even numbers is: ” << evenSum(n);
return 0;
}

3 . Write a program to Get mark 1 to mark 5 and create a method which has argument pass mark if mark 1 to mark 5 are greater than pass mark ,return true ,else return false
#include<stdio.h> void main() { int m1,m2,m3,total; float per; clrscr(); printf("Enter 3 Nos."); scanf("%D%D%D",&m1,&m2,&m3); total=m1+m2+m3; per=total*100/300; if(per>=60&&per<=100) printf("You are 1st :"); else if(per>=50&&per<=60) printf("You are 2nd"); else if(per>=40&&per<=50) printf("You are 3rd"); else printf("You are Fail"); getch(); }
