Assembly Language Coding Problems using the alphabet? Please help. Thanks.

Assemble, link, and run the "printAlpha.s" (shown at bottom) assembly language program using the following steps:

1) as printAlpha.s -o printAlpha.o 2) gcc printAlpha.o 3) ./a.out

The program prints the alphabetical characters from 'a' to 'z' on one line as follows:

$ ./a.out abcdefghijklmnopqrstuvwxyz $

Make 2 copies of the printAlpha.s file, and call them mountainTerrain.s, and triangle.s

PROBLEMS:

Problem 1: Edit the mountainTerrain.s file and change the code to alternature between upper and lower case characters while printing the alphabet. The output should be as follows:

$ ./a.out AbCdEfGhIjKlMnOpQrStUvWxYz $

Problem 2: Edit the triangle.s file and change the code to print a triangle using lower case characters. The output should be as follows:

$ ./a.out abcdefghijklmnopqrstuvwxyz abcdefghijklmnopqrstuvwxy abcdefghijklmnopqrstuvwx abcdefghijklmnopqrstuvw abcdefghijklmnopqrstuv abcdefghijklmnopqrstu abcdefghijklmnopqrst abcdefghijklmnopqrs abcdefghijklmnopqr abcdefghijklmnopq abcdefghijklmnop abcdefghijklmno abcdefghijklmn abcdefghijklm abcdefghijkl abcdefghijk abcdefghij abcdefghi abcdefgh abcdefg abcdef abcde abcd abc ab a $
