C :: Converting A String Array Into Uppercase Letters From File

Apr 19, 2013

I am new to coding Here is the problem. Have a program prompt the user for a filename to open. Change every alphabetic character in the file to a capital letter. Numbers and special characters should not be changed. Print the output to the screen.

Here is my code so far but i am only returning the last line of text capitalized from the file. I am trying to get the program to display all of the three lines of text from the file capitalized. The program displays the file correctly before i try and convert everything toupper();

Code:

Code: #include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <ctype.h>
int main()
{
char line[81], filename[21];
int i;
FILE *inFile;

[Code]...

C/C++ :: Function That Generates A Random String Of Uppercase Letters

Apr 19, 2014

I need to write a C function that generates a random character array (i.e. string) of uppercase letters - getchar and putchar are the only IO functions that I can use. Below is what I have already - I am iterating for as many times as I am required to, and am modulating rand() by 25, (total letters in the alphabet). I'm trying to see how to get the random letter from the % 25, and also how to do this without toupper() [not sure if I can use that function].

void getRandomStr()){
char str[40];
for (int i = 0; i < 40; i++){
char c = rand() % 25);
str[i] = toupper(c);
}}

C :: Detecting Number Of Uppercase Letters?

Mar 20, 2014

Just wrote this extremely simple program but it seems to be malfunctioning. It counts correctly the number of uppercase letters in a string so long as i don't use the space-bar. once I add a space it only counts the number of uppercase letters of the first word..

printf("I ..........ing love programming");

Code:

#include <stdio.h>
main()
{
char text[200];
int i = 0;
int uppercase = 0;

C++ :: Number Of Characters / Operators / Uppercase Letters And Numerical Digits

May 5, 2014

I have to code a simple program who determining the number of Characters (A character could be any alphabets, digits, punctuation marks, or special , Operators ( Operators are those symbols that are used in mathematica expression, such as,'+', '*', '/', '-', and so on.), Uppercase letters (Uppercase characters are those from A..Z) and Numerical digits ( A digit is any of the Hindu-Arabic numerals from 0..9). Why the output is wrong!

#include <iostream>
#include <string>
#include <fstream>
#include <cstdlib>
#include <iomanip>
using namespace std ;
int main() {
char text;

[Code] .....

This is my input file This is a possible factorial function in a programming language called LISP

(defun factorial (n)
(if (< n 2)
1
(* n (factorial (1- n)))))

This is my output:

The number of characters = 113
The number of operators = 3
The number of numerical digits = 3
Uppercase letters = 5

I think that "characters" is wrong, but I do not know why !

C++ :: Text Adventure Game - Converting Input To Uppercase?

Jul 16, 2014

I'm trying to create a sort of text-adventure game, but rather than having to check for the input being uppercase or lowercase, I'd rather convert it before checking it in an if statement.

I've created a function, and I know it works because when I print the output, it shows up capitalized, however when I check it with an if statement, it doesn't pass.

Here is my code:

#include <iostream>
using namespace std;
void stringUppercase(string x) {
int i;
for (i = 0; i < x.length(); i++) {

C/C++ :: Converting Letters To Numbers In A Loop

Jan 25, 2014

I have my program working, as far as converting the letters to numbers, but i want be able to enter as many numbers as i want. so i figured i could put into a loop asking a question at the end. question being whether the user wants to enter another number or not. also i'm assuming the user enters exactly 7 letters each time. this is my code so far.

const int arSize = 9;
char letters[arSize];
int numbers[arSize];
int count = 0;
cout << "Enter a telephone number expressed in letters. (e.g. CALL loan ( it is not case sensetive))";
for (int i = 0; i < 7; i++,count++)

C :: Strcpy - How To Update Old String In Stars Array With New That Includes Correct Letters

Apr 25, 2013

This for loop replaces the stars ******** in an array that contains a word to be guessed with the correct letter (c) that the user inputs if the word contains that letter.

Problem: After every guess the same hidden string of stars ******* is displayed instead of ex: ***W**** (assuming W was entered by the user)

How can I update the old ******** string in the Stars array with the new string that includes the correct letters chosen, so after every correct guess at a letter in the word a new string is displayed including the correct letters chosen?

I'm pretty sure I have to use strcpy but not sure how to implement it using a loop.

Code:
for(i = 0; i < strlen(unscrambledWord); i++) {
if(unscrambledWord [i] == c) {
Stars[i] = c;
} }

C++ :: Converting String To Char Array

Mar 30, 2014

In this program, I have to ask the user for an employee, then the program will check to see if the file for that employee exist, if it doesnt then it will automatically create the file.

ReadNew function reads the file....check to see if it exist

CreateNew function creates a new file.

In my code I have no problem with the first part of reading file.. and my createnew function works in other programs where I am asking for input of file name to create the file name. However in this code I cannot figure how to automatically pass the input filename from the ReadNew function to the CreateNew function. I can't ask the user to enter the name a second time, so I have to pass the input filename into both functions. Here is my code.

Code:

//Create a file, append to it, and read it.
#include <iostream>
#include <fstream>
#include <string.h>
#include <stdio.h>
using namespace std;
char filename[256];
string n;
string filelist;
void CreateNew(ofstream & FileNew);

C/C++ :: Input Lowercase String / Output Uppercase String

Dec 3, 2014

write a program that prompts the user to input a string and outputs the string in uppercase letters. (Use a character array to store the string.) Does this follow the criteria? This program is very similar to one I found on these forums but I have one problem, it outputs everything backwards! EX: dogs will output to SGOD. What I need to do to make it output correctly, I think it may have to do with getline?

#include <iostream>
#include <cctype>
#include <cstring>
using namespace std;
int main() {
char let[100];
cout << "Enter what you would like to be UPPERCASE: ";
