Thread: Combine 3 files in C

I am beginer in C programing and need some help. I have to combine 3 files.
file1.txt:
1 Gregor Schlierenzauer
2 Martin Koch
3 Janne Happonen
4 Robert Kranjec
5 Janne Ahonen

file2.txt:
1 197.7
4 193.3
2 187.8
3 186.6
5 186

file3.txt
5 218.7
2 195.6
4 190.1
1 182.5
3 181

Output should be:
1 Janne Ahonen 404.7
2 Robert Kranjec 383.4
3 Martin Koch 382.6
4 Gregor Schlierenzauer 380.2
5 Janne Happonen 367.6

Thank you for any help!

So far I have this:

Code:

#include <stdio.h>

int main(int argc, char *args[]){
	FILE *smucarji, *serija1, *serija2;

	char tekmovalci[50];
	double rezultat1[10], rezultat2[10];
	int index;
	char index1[100], index2[100];
	double tocke;
	char tocke1[100], tocke2[100];


	smucarji = fopen("smucarji.txt", "r");
	if((smucarji != NULL)){
		while(!feof(smucarji)){
			for(int i = 0; i < 10; i++){ 
				fscanf(smucarji, "%d", &index);      //prebere startno številko
				fgets(tekmovalci, 50, smucarji);         // prebere ime in priimek      
			}
		}
	}
	fclose(smucarji);

	serija1 = fopen("serija1.txt", "r");
	if((serija1 != NULL)){
		while(!feof(serija1)){
			for(int i = 0; i < 10; i++){ 
				fscanf (serija1, "%s %s", index1, tocke1);
					index = atoi(index1);
			  		tocke = atof(tocke1);
			    		rezultat1[index-1] = tocke; //poz-1 je glavna stvar da ti da k pravilnemu skakalcu
			}
		}
	}
	fclose(serija1);

	serija2 = fopen("serija2.txt", "r");
	if((serija2 != NULL)){
		while(!feof(serija2)){
			for(int i = 0; i < 10; i++){ 
				fscanf (serija2, "%s %s", index2, tocke2);
					index = atoi(index2);
			  		tocke = atof(tocke2);
			    		rezultat2[index-1] = tocke; //poz-1 je glavna stvar da ti da k pravilnemu skakalcu
			}
		}
	}
	fclose(serija2);

	return 0;
}

Now I need printf. Help please
