Question

Write a program to read 20 integers from a file named data.txt and print the largest and smallest values in the console window. In the file data.txt. each integer is written in a separate line. An example of a pyramid of base 5 1. Write everything in the main function Print a pyramid of base 5 2. Write everything in the main function. Print a pyramid of base n, where n is an odd integer between 1 and 9 entered by the user. Your program should validate user input. If it's not an odd integer, ask the user so reenter the number. 3. Write a function named PrintPyramid to print a pyramid. PrintPyramid has one value parameter of type int, named m in the main function, call PrintPyramid m will get the integer entered by the user, which is between 1 and 9. 4. On the top of (3).add statements in the main function to print all pyramids which have base less than or equal to an integer between 1 and 9 entered by the user. Please print an empty line between pyramids. For example, suppose the user enters 5 your output should be like [empty line] [empty line]

Explanation / Answer

2nd one pyramid:

  #include<iostream.h>  #include<fstream.h>  #include<string.h>  #include<cstdlib.h>  using namespace std;  int main(){     std:ifstream inputFile("data.txt");      string fileName;int value, x;      cout <<"Enter the file name: ";      getline(cin, fileName);    inputFile.open(fileName.c_str());//openingif(inputFile.fail()){         cerr <<"Error Opening File"<< endl;  return(1);  }      cout <<"Pick a number between 1 through 100. ";      cin >> value;do{      cout <<"Pick a number between 1 through 100. ";int value;      cin >> value;}while(value <1|| value >100);      int number;int count =0;      infile >> number;  while(!inputFile.eof()){if(number == x){              sum1++}          inputFile >> number;}      cout << sum1;  while(!inputFile.eof()){         inputFile >> word;  if(word =="input"){              count++;}}      inputFile.close();  return (0);  }  

2nd one pyramid:

  #include<stdio.h>  #include<cononio.h>  int main()  {  int i,s,row,p=0;      printf("Enter the number of row: ");      scanf("%d",&rows);  for(i=1;i<=row;++i)  {  for(s=1;s<=row-i;++s)  {             printf("  ");  }  while(p!=2*i-1)  {             printf("* ");  ++p;  }          p=0;          printf(" ");  }  return (0);  getch();  }
