Thread: Struct array and find max.

Hello everyone. I am new to this forum and begginer in C programming.

So I have to make a struct (named country) and I need to scanf the name of a country, population and the capital of a country. The problem is that I need to find the max population and printf the country and the capital of this.

So I scanf USA, 100000, Washington and Greece, 1000, Athens etc.

Then I have to printf USA, 100000, Washington.

That's all I wrote.

Code:

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

#define N 2

struct country {
    char c_name[30];
    int population;
    char capital[30];
};

/*
 * 
 */
int main(int argc, char** argv) {
    
    struct country xwra[N];
    
    int max = 0;
    int i;
    
    for (i=0; i<N; i++){
        printf("\nGive country name.\t");
        scanf("%s", xwra[i].c_name);
        printf("\nGive the population.\t");
        scanf("%d", &xwra[i].population);
        printf("\nGive the capital.\t");
        scanf("%s", xwra[i].capital);
        if (xwra[i].population > max)
            max = xwra[i].population;
    }
    
    

    return (EXIT_SUCCESS);
}

So how to printf the max population with name of the country and the capital???

Have two variables.

int maxPop = 0;
int maxPos = 0;

MaxPop tracks the max population, pretty much like you're doing at the moment.
MaxPos tracks the value of i, so you can get back to it later on.
