Y2K Problem Detector

Write a program that asks a user for their birth year encoded as two digits (like "62") and for the current year, also encoded as two digits (like "99"). The program is to correctly write out the users age in years.

Input Format:

Input consists of 2 integers. The first integer corresponds to the last 2 digits of the birth year. The second integer corresponds to the last 2 digits of the current year.

Output Format: 

Refer sample input and output for further formatting specifications. 

Sample Input and Output: 

[All text in bold corresponds to input and the rest corresponds to output] 

Enter Year of Birth 

62 

Enter Current year 

99 

Your age is 37 

The program will have to determine when a two digit value such as "62" corresponds to a year in the 20th century ("1962") or the 21st century. Here is another run of the program, where "00" is taken to mean the year 2000:

Enter Year of Birth 

62 

Enter Current year 

00 

Your age is 38 

Assume that ages are not negative. Another run of the program: 

Enter Year of Birth 

27 

Enter Current year 

07 

Your age is 80 

In the following run, the age of the person could be 6 or 106 depending on the assumptions. Assume that the age will always be less than or equal to 100. 

 Enter Year of Birth 

01 

Enter Current year 

07 

Your age is 6 

Enter Year of Birth 

62 

Enter Current year 

99 

Your age is 37

Code:

  #include<stdio.h>
int main(){
  signed int current, birth, a;
  printf("Enter Year of Birth\n");
  scanf("%d",&birth);
  printf("Enter Current year\n");
  scanf("%d",&current);  
  if(current<birth)
  {
    birth=100-birth;
    a=birth+current;
    printf("Your age is %d",a);
  }
  else
  {
  printf("Your age is %d",current-birth);
  }
  return 0;
}
