Program:

#include <stdio.h>

int main()
{
    int i, j;
    // Initializing array
    char original_array[] = {'a','b','c','d','e'};
    // Get length of array
    int length  = sizeof(original_array)/sizeof(original_array[0]);
    // Loop iterates till the length of the array 
    for (i = 0; i < length; ++i) {
        // Loop iterates till the i value
        for (j = 0; j <= i; ++j) {
            // Printing the characters in the array
            printf("%c ", original_array[j]);
        }
        // Prints new line
        printf("\n");
    }

    return 0;
}

Output:
