Selectively reading string part of a file using C - c

Question

I have a .txt file with strings each line and a number assigned to each string and a - in between the string and the number.
Now I want to read only the string part not the number or the - in between, store them in an array and write only the strings in another file.
I used the following approach:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX 100
struct String {
long long int num;
char name[50];
char C;
} S[MAX], temp;
void file_write(int n, struct String S[]) {
FILE *pp;
pp = fopen("std3.txt", "a"); //second file where I want to write only string part.
for (int i = 0; i < n; i++) {
fprintf(pp, "%s", S[i].name); //storing the strings in another file
fputs("\n", pp);
}
fclose(pp);
}
int main() {
int n;
FILE *fp;
fp = fopen("str.txt", "r");
printf("Enter the number of strings : ");
scanf("%d", &n);
for (int i = 0; i < n; i++) {
fscanf(fp, " %[^\n]", S[i].name);
fscanf(fp, "%lld", &S[i].num);
fscanf(fp, "%c", &S[i].C);
}
file_write(n, S);
fclose(fp);
return 0;
}
But I'm getting an undesirable output:

Answer 1

Here is a simple solution using fscanf() and the * assignment suppression option:
#include <stdio.h>
int main() {
int n = 0;
FILE *fp = fopen("str.txt", "r");
// second file where I want to write only string part.
FILE *pp = fopen("std3.txt", "a");
if (fp == NULL || pp == NULL) {
fprintf(stderr, "cannot open files\n");
return 1;
}
printf("Enter the number of strings: ");
scanf("%d", &n);
for (int i = 0; i < n; i++) {
char name[50];
int c;
if (fscanf(fp, "%*d - %49[^\n]", name) == 1) {
fprintf(pp, "%s\n", name);
/* flush any extra characters and the newline if present */
while ((c = getc(fp)) != EOF && c != '\n')
continue;
} else {
break;
}
}
fclose(fp);
fclose(pp);
return 0;
}

Scanf (and its variations) is a very powerful function... I think the following line is what you want.
for(int i=0;i<n;i++)
{
fscanf(fp, "%*[^A-Z]%[^\n]", S[i].name);
}
A brief description of what it does is: It discards any character that is not a capital letter then reads everything from the first capital letter until the end of line.
If the names are allowed to start with lowercase, you can change it to:
fscanf(fp, "%*[^A-Za-z]%[^\n]", S[i].name);
