c - Incorrect output using strcmp

Question

I'm doing the day 8 of the 30 days of code in HackerRank and I am having a problem with strcmp. The code asks the user for names of people and their numbers, then asks for other names, if a name wasn't entered before, then it outputs Not found, but if it was then it outputs the name and his number. But for some reason, the output only works in the last loop of the for statement. Code:

#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>

typedef struct {
    char name[100];
    int number;
} phonebook;

int main() {
    int n = 0;
    do {
        scanf("%i", &n);
    } while (n < 1 || n > 100000);
    
    int i = 0;
    phonebook people[n];
    
    for (i = 0; i < n; i++) {
        scanf("%s %i", people[i].name, &people[i].number);
    }
    
    char othernames[n][100];
    
    for (i = 0; i < n; i++) {
        scanf("%s", othernames[i]);
    }
    
    for (i = 0; i < n; i++) {
        if (strcmp(othernames[i], people[i].name) == 0) {
            printf("%s=%i
", people[i].name, people[i].number);
        } else {
            printf("Not found
");
        }
    }
    return 0;
}

Answer 1

You didn't find the othernames from the beginning to end to compare peopleevery time, so you need to replace

for (i = 0; i < n; i++) {
  if (strcmp(othernames[i], people[i].name) == 0) {
    printf("%s=%i
", people[i].name, people[i].number);
  } 
  else {
    printf("Not found
");
  }
}

to

bool found = false;
for (i = 0; i < n; i++) {
  for ( j = 0 ; j < n ; j++ ) {
    if (strcmp(othernames[j], people[i].name) == 0) {
      printf("%s=%i
", people[i].name, people[i].number);
      found = true;
    } 
  }
}

if ( found == false ) printf("Not found
");
