Question

Need help to write a code in c.

here are some values

| 123417 102245 5469 35 6678 1014

And here are values of a,b and c. a = 1, b = 0.8, c= 0.5. equation for total is = (A*a) + (B*b) + (C*c)

I need help to write a code that iterates values of a,b,c in order of a > b > c to get h =2. h is random variable. It will continue iterating value of a,b,c until it gets h = 2.

Answer 1

#include<stdio.h>
#include<stdlib.h>
int main()
{
FILE *fp;
char buffer[100];
int i=0,arr[10],sum,k;
float a=1,b=0.8,c=0.5,h,total;
fp = fopen("text.csv","r");
fgets(buffer, sizeof(buffer), fp);
//reading the file line by line
while(fgets(buffer, sizeof(buffer), fp) != NULL)
{
sum = 0;
i=0;
k = 0;
   //In each line there are three numbers seperated by ','(12,34,17) so the three number are splited and stored into an array
while(buffer[i]!='\n')
{
if(buffer[i]!=',')
{
sum = sum*10+(int)(buffer[i]-'0');
}
else
{
       //if there is a ',' that implies the number is ended so we will store the number into array
arr[k++]=sum;
       //here if we print arr[k] it will give the corresponding number
sum = 0;
}
i++;
}
arr[k++]=sum;
//calculating the total
total = arr[0]*a+arr[1]*b+arr[2]*c;
   //printing the total sum
printf("%f\n",total);
   //In the question it is mentioned that h is a random variable and until h=2 we have to perform iterations.Since the csv file contains five rows we have used %5 here.it will generate a number between 1 to 5.whenever it generates 2 we will stop the iterations.
h = rand()%5+1;
if(h==2)
{
//stop iterating when h =2
break;
}
  
}
}
