PROGRAM 96

Object

Write a program to print a string, starting with the first character increasing one character in the following line until the end of the string is reached.

Algorithm

1. Declare a string word up to 20 characters and integer variables length, i and j.
2. Read string word.
3. Find length of string word, using strlen(word).
4. Repeat FOR i = 1 to length of string by 1
   • Repeat FOR j = 0 to (i-1) by 1
     • Write word[j].
     • Advance a line.
   • [End of inner FOR loop.]
   • [End of outer FOR loop.]
5. Exit.

using namespace std;

int main()
{
  char word[20];
  int length, i, j;
  cout << "Enter a word up to 20 characters: ";
  cin.getline(word, 20);
  length = strlen(word);
  
  for (i = 1; i <= length; i++)
  {
    for (j = 0; j < i; j++)
      cout << word[j];
    cout << endl;
  }
  return 0;

int main()
{
  char word[20];
  int length, i, j;
  printf("\nEnter a word up to 20 characters: ");
  gets(word);
  length = strlen(word);
  for(i=1; i<=length; i++)
     {
     for(j=0; j<i; j++)
        printf("%c", word[j]);
