C Programming Question

Consider this data sequence: "3 11 5 5 5 2 4 6 6 7 3 -8". Any value that is the same as the immediately preceding value is considered a CONSECUTIVE DUPLICATE. In this example, there are three such consecutive duplicates: the 2nd and 3rd 5s and the second 6. Note that the last 3 is not a consecutive duplicate because it was preceded by a 7.

Write some code that uses a loop to read such a sequence of non-negativeintegers, terminated by a negative number. When the code exits the loop it should print the number of consecutive duplicates encountered. In the above case, that value would be 3.

Explanation / Answer

Please find the required program along with its output. Please see the comments against each line to understand the step.

#include <stdio.h>

int main()
{
int prev=-1,curr, count=0;
printf("Enter numbers(press negative number to exit): "); //read the first number
scanf("%d",&curr);
  
while(curr >= 0){ //iterate the loop untill the user input number is non negative
if(curr == prev) //if the current user input number is equal to previous number
count++; //increment the count
prev = curr; //set assign current number to previous number
scanf("%d",&curr); //read the next number
}
  
printf(" Consecutive duplicate count = %d ",count); //print the result Consecutive duplicate count

return 0;
}

OUTPUT:

Enter numbers(press negative number to exit):   
3   
11
5   
5   
5   
2   
4   
6   
6   
7   
3   
-8
  
Consecutive duplicate count = 3
