Getting user input doesn't work correctly

Question

I am writing a simple program in C using structs. The user needs to enter some values for the struct - a name and age. After I enter the data for the first time, the second time the program just skips one of the fields and only wants me to enter the second field of the data. I can't figure out what's wrong.

    struct Person {

        char name[20];
        int age;
    };

void main(){

    struct Person pArray[10];
    for (int i = 0; i < 10; i++) {
        printf("Please enter a name and age:\n");
        printf("Name: ");
        fgets(pArray[i].name, 20, stdin);
        printf("Age: ");
        scanf("%d", &pArray[i].age);
    }
}

As you can see, after entering Jonathan and 45 for the first time, the second time it skipped the name and wants only the age. Why is this happening?

I try not to mix formatted and unformatted input (eg, fgets and scanf ). Here is your program using only fgets for input:

#include <stdio.h>

struct Person {
    char name[20];
    int age;
};

int main(){
    struct Person pArray[10];
    char numberBuffer[20];
    for (int i = 0; i < 10; i++) {
        printf("Please enter a name and age:\n");
        printf("Name: ");
        fgets(pArray[i].name, 20, stdin);
        printf("Age: ");
        fgets(numberBuffer, 20, stdin);
        sscanf(numberBuffer, "%d", &pArray[i].age);
    }
}
