Answer to Question #253846 in C++ for Bryce

Question

Write a Program: DNA Sequence Analysis

Every DNA sequence consists of four nucleotides: Adenine, Thymine, Cytosine, and Guanine,

referred to by the first letters of their chemical names (A, T, C, and G). I have provided an

entire DNA sequence in the file

dnaSequence.txt.

You goal is to provide a report of the number of each nucleotide within the sequence, and the

percent each nucleotide makes up of the total. You should include your output file in the

submission in addition to our usual submission format (console output + code).

Answer 1

#include <bits/stdc++.h>
using namespace std;

void printUpperHalf(string str) {
	char first, second;
	int pos = 0;
	for (int i = 1; i <= 4; i++) {
		first = str[pos];
		second = str[pos + 1];
		pos += 2;
		for (int j = 4 - i; j >= 1; j--) cout << " ";
		cout << first;
		for (int j = 1; j < i; j++) cout << "--";
		cout << second << endl;
	}
}
void printLowerHalf(string str) {
	char first, second;
	int pos = 0;
	for (int i = 1; i <= 4; i++) {
		first = str[pos];
		second = str[pos + 1];
		pos += 2;
		for (int j = 1; j < i; j++) cout << " ";
		cout << first;
		for (int j = 4 - i; j >= 1; j--) cout << "--";
		cout << second << endl;
	}
}
void printDNA(string str[], int n) {
	for (int i = 0; i < n; i++) {
		int x = i % 6;
		if (x % 2 == 0) printUpperHalf(str[x]);
		else printLowerHalf(str[x]);
	}
}

int main() {
	int n = 8;
	string DNA[] = { "ATTAATTA", "TAGCTAGC", "CGCGATAT", "TAATATGC", "ATCGTACG", "CGTAGCAT" };
	printDNA(DNA, n);
	return 0;
