Question

Write a C program that reads a list of positive integers from a file named "input.txt." and count number of odd integers and even integers and prints the results to another file called "results.txt". Please submit both the input and results files along with the c program.

Answer 1

Answer:-

code:

#include<stdio.h> int main() {   FILE *f;                f=fopen("input.txt","r"); // file input         int a;  int counter_odd=0;      int counter_even=0;     while(fscanf(f," %d",&a)==1) //scanning integers and counting no. of odds and evens         {        if(a%2==0)             counter_even++;                 else            counter_odd++;  }       fclose(f);      FILE *o;        o=fopen("results.txt","w");     fprintf(o, "no. of even integers: %d\n", counter_even); // output to results.txt        fprintf(o, "no. of odd integers: %d\n", counter_odd);   fclose(o);       }

input.txt

 8 10 11 12 13 14 15 16 17 18

results.txt

no. of even integers: 6 no. of odd integers: 4 

instructions:-

1) you just have to create an input.txt file on the location where your program is saved

2) results.txt file will be created automatically by the program.

output:-

1)input.txt

2)results.txt
