Question

In c language. I have to read 3 files and used the numbers in the file in a program. An example of the 3 files are below. How do read the numbers, I realize it’s with arrays. The input won’t have more than 100 lines but it can have less n

3. Input Files The filename includes the variable name and the sensor number as: variable name <sensor id txt For example "BT 0001.txt" is the file that contains the body temperature data collected for patient ID 0001 NOTE: al time stamps (days) are integers-and all data are collected within 100 day period. Some data on some days may be missing- in this case you will need Linear Interpolation BT files have the following format time stamp value> For example 0034 0054 0074 97.5 97.4 97.6 BP files have the following format: time stamp «В PD> BPS For example 0024 0044 0064 78 79 76 118 119 119 HR files have the following format: Stime stamp value> For example 0034 0035 0036 96 94 98

C CODE:

#include <stdio.h>

int main()
{
//CHANGE THE PATH OF FILES ACCORDINGLY
char *filepath1 = "M:\data1.txt"; //path for BT file
char *filepath2 = "M:\data2.txt"; //path for BP file
char *filepath3 = "M:\data3.txt"; //path for HR file

FILE *inputFile1;
FILE *inputFile2;
FILE *inputFile3;

//function to open a file and keep the contents in a file variable
inputFile1=fopen(filepath1,"r");

//Declaring array for Storing values of BT file in arrays
long timestamp_BT[100];
float value_BT[100];

//Declaring array for Storing values of BP file in arrays
long timestamp_BP[100],BPS[100],BPD[100];

//Declaring array for Storing values of HR file in arrays
long timestamp_HR[100],value_HR[100];

int t1=0,t2=0,t3=0; //will store No_of_entries in table 1 2 & 3 respectively
if(inputFile1==NULL)
{
printf("Input File 1 cannot be opened.");
return 0;
}
printf("****File1 content****\n");
while(!feof(inputFile1)) // while loop while which run until end of file is reached
{
fscanf(inputFile1,"%ld %f",&timestamp_BT[t1],&value_BT[t1]);
printf("\n%ld %.2f",timestamp_BT[t1],value_BT[t1]);
t1++;
}
printf("\n\n");
fclose(inputFile1);

inputFile2=fopen(filepath2,"r");
if(inputFile2==NULL)
{
printf("Input File 2 cannot be opened.");
return 0;
}
printf("****File2 content****\n");
while(!feof(inputFile2))
{
fscanf(inputFile2,"%ld %ld %ld",&timestamp_BP[t2],&BPD[t2],&BPS[t2]);
printf("\n%ld %ld %ld",timestamp_BP[t2],BPD[t2],BPS[t2]);
t2++;
}
printf("\n\n");
fclose(inputFile2);

inputFile3=fopen(filepath3,"r");
if(inputFile3==NULL)
{
printf("Input File 3 cannot be opened.");
return 0;
}
printf("****File3 content****\n");
while(!feof(inputFile3))
{
fscanf(inputFile3,"%ld %ld",&timestamp_HR[t3],&value_HR[t3]);
printf("\n%ld %ld",timestamp_HR[t3],value_HR[t3]);
t3++;
}
printf("\n\n");
fclose(inputFile3);

printf("No_of_entries_in_table_1=====%d\nNo_of_entries_in_table_2=====%d\nNo_of_entries_in_table_3=====%d",t1,t2,t3);
return;
}
