Studi Kasus Mencari Nilai IPK C++

1. Analisi Masalah
=>Mengitung IPK mahasiswa

2. Analisis

    - Input jumlah sks dan nilai dalam bentuk huruf [A-E]

    - Output nilai IPK berdasarkan jumlah sks dan nilai huruf

3. Algoritma

Procedure IPK (input/output matkul[50] ::char , jmk :: integer, bsks::integer)
Deklarasi
                x -> integer
                bernilai[100]->integer
                mutu[100]->integer
