Using malloc()

 #include<stdio.h> 

#include<stdlib.h> 

int main(){

    int *ptr;

    // Sizeof operator in C

    // printf("The size of int on my pc is %d\n", sizeof(int));

    // printf("The size of float on my pc is %d\n", sizeof(float));

    // printf("The size of char on my pc is %d\n", sizeof(char));

    ptr = (int *) malloc(6 * sizeof(int)); 

    for(int i=0; i<6;i++){

        printf("Enter the value of %d element: \n", i); 

        scanf("%d", &ptr[i]);

    }

    for(int i=0; i<6;i++){

        printf("The value of %d element is: %d\n", i, ptr[i]); 

    }

    return 0;
