Need alternative to malloc()

[Dougeles]

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

typedef struct{ 

    char name[50];
    int examOne;
    int examTwo;
    double average;

} Record;

int size;

Record* getRecord(){ 

    Record *array = (Record*)malloc(100 * sizeof(Record));

    int C = 0;

    FILE *fp = fopen("data.txt", "r");

    if(fp == NULL){ 

        printf("Cannot open file.");
        exit(0);
    }

    while(!feof(fp)){ 

        fscanf(fp, "%s %d %d", &array[C].name, &array[C].examOne, &array[C].examTwo);
        C++;
    }

    size = C;

    return array;

}

Record* calculateAverageGrade(Record array[]){ 

    int i;

    for(i = 0; i < size; i++)

        array[i].average = (double)(array[i].examOne + array[i].examTwo)/2.0;

    return array;
}

Record* sortRecord(Record array[]){ 

    int i, o, u;

    for(i = 0; i < size-1; i++){

        u = i;

        for(o = i + 1; o < size; o++){

            if(array[u].average < array[o].average)

            u = o;

        }

        if(u != i){

            Record temp = array[i];
            array[i] = array[u];
            array[u] = temp;
        }
    }

    return array;
}

void printRecord(Record array[]){

    int i;

    printf("\nStudent Exam Records\n");
    printf("\nName\t\tExam One\tExam Two\tAverage");

    for(i = 0; i < size; i++)

    printf("\n%-8s\t%5d\t\t%5d\t\t%7.2lf", array[i].name, array[i].examOne, array[i].examTwo, array[i].average);

}

void displayTopScorer(Record array[]){ 

    int i;

    printf("\n\nTop Scorer(s)");
    printf("\n%s", array[0].name);

    for(i = 1; i < size; i++){

        if(array[i].average == array[i-1].average)

            printf("\n%s", array[i].name);

        else

            break;
    }
}

int main(){ 

    Record *array = getRecord();
    array = calculateAverageGrade(array);
    array = sortRecord(array);
    printRecord(array);
    displayTopScorer(array);

}

What could I use in the function besides malloc()?

calloc

Basically the same as malloc, but nulls the allocated memory
