CSI 250L Lab 1 Solution, Spring 2012

American University of Science & Technology Department Of Computer Science CSI 250L – Computer Programming-II Lab Fall 2011/2012 Lab Work 1 Solutions prepared by: Dr. Saeed Raheel Part 3 - Review Functions and arrays of integers : Write a program to allow the user to input N positive integers and store them in an array, arr, of 100 cells.(let N be the first input by the user) The program should print the content of arr sorted in ascending order. #include <iostream> using namespace std; void printArray(int a[], int size) { for (int i=0;i<size;++i) cout << a[i] << " "; cout<<endl; } void sortAscending(int a[], int size) { int temp; for (int i=0;i<size;++i) for (int j=0;j<size-1;++j) { if (a[j]>a[j+1]) { temp = a[j]; a[j]=a[j+1]; a[j+1]=temp; } } } int main() { int N; int arr[100]; cout << "Please enter the number of values to be entered : "; cin >> N; cout << "Please enter " << N << " numbers :" << endl; for (int i=0;i<N;++i) cin >> arr[i]; sortAscending(arr, N); cout << "The array elements sorted in ascending order : " << endl; printArray(arr, N); system("pause"); return 0; } Part 4 - Review Functions and arrays of characters : Write a program that inputs a word into an array S1. The program should store in an array S2 the reverse of S1, and in S3 the content of S1 converted to capital letters. #include <iostream> using namespace std; int getArraySize(char a[]) { int i; for (i=0;a[i]!='\0';++i); return i; } void printArray(char a[]) { for (int i=0;a[i]!='\0';++i) cout << a[i]; cout<<endl; } void reverse(char a[], char b[]) { int size = getArraySize(a); for (int i=0;a[i]!='\0';++i) b[i] = a[size-i-1]; b[size]='\0'; } void capitalize(char a[], char b[]) { int i; for (i=0;a[i]!='\0';++i) if (a[i]>='a' && a[i] <='z') b[i] = ('A' + (a[i]-'a')); else b[i] = a[i]; b[i] = '\0'; } int main() { const int size = 25; char s1[size], s2[size], s3[size]; cout << "Please enter a word : "; cin >> s1; reverse(s1, s2); cout << "The word in reverse order : "; printArray(s2); cout << endl; capitalize(s1, s3); cout << "The word in capital letters : "; printArray(s3); cout << endl; system("pause"); return 0; }
