City A population is 68000, decreasing at a rate of 80 per year City B having population 42000 increasing at a rate of 120 per Year. In how many years both the cities will have same population ?

City A population = 68000
Amount of decrease = 68000-80X
City B population = 42000
Amount of increase = 42000+120x

If both cities will have same population then

68000-80x = 42000+120x
68000-42000 = 120x+80x
26000 = 200x
x = 26000/200
Ans = 130
In 130 years both cities will have same population

Check:

City A population = 68000-80* 130
= 68000-10400
= 57600
City B population = 42000+ 120*130
= 42000+15600
= 57600

Write the test cases on prime number with result ?

Let the prime number be n.
Divide the number n by 1 remainder=0 pass.
Divide the number n by n remainder=0 pass.
Divide the number n by 2 remainder!=0 pass.
Divide the number n by up to n-1 and if remainder not equal zero, then it is a prime number.

Prime Number Algorithm

Example

 
function primeTester (n) {
 //take out edge case 0 and 1
 if(n<=1) 
 return false;
  
 //go from 3 since 2 is a prime number
 for(var i=3; i   //check if n is divisible by i
   if(n%i ===0 ) 
   return false
 }
 
 //if passed all out test
 return true;
}

What is class/object diagram ?

Java Class:

A class is an entity that determines how an object will perform and what the object will contain.
In other words, it is a blueprint or a set of instruction to build a specific type of object.

Syntax:

 
class ClassName {
   // variables
   // methods
}

Java Objects:

When class is defined, only the condition for the object is defined.
No memory or storage is allocated.
To access members defined within the class, you need to create objects.

Syntax:

ClassName ReferenceVariable = new ClassName();

What is the Output ?

 
main () 
  {
  char *p1="Name"; 
  char *p2; 
  p2=(char *)malloc(20); 
  while(*p2++=*p1++); 
  printf("%s\n",p2); 
  } 

Answer : NULL

We are incrementing the pointers p1,p2.
When it reached the end of the string, *p2 points to NULL.
We have lost the address of the starting position.
