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);
}}

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]...

/* Program is to let the user enter a string and will output the sting in all uppercase letters. */
#include <cctype>
#include <iostream>
#include <string>
using namespace std;
char str1[80];
[Code] ....
I am trying to get the cin.get working where the user is allowed to enter an 80 character string and how to do that.

My problem says: Have the user enter a number from 1-80 then print out a string of random letters(a to z lowercase) of that length.
I have been able to enter the number and output the correct amount of letters but i can't figure out how to get them to be in a random order and not in alphabetical. Here is what I have so far.
#include <iostream>
using namespace std;
int main() {
int i=0;
int num;
cout<<"How many letters do yu want in your random string?";

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;
printf("Enter text:");
scanf("%s", text);

The user thinks of a number from 0 to 100 and the program tries to guess it. The problem is, I'm new to random numbers and use a function to generate them that isn't my own. It generates the same numbers each time the program runs, here are screen shots:
Run 1: [URL] .....
Run 2: [URL] .....
I read something about seeding or something, if I need it, must don't give me the answer. If you have the liberty of time explain more to me about the random business.
Here is my code:
#include <iostream>
#include <cstdlib>
#include <iomanip>
#include <unistd.h>
#include <string>
#include <ctime>
using namespace std;
int rand_lim(int limit) {
[Code] ....

char ch;
int uppercase=0;
int lowercase=0;
file.open(pav.c_str());
while(!file.eof()) {
[Code] .....
So I need to count uppercase and lowercase letters from file, and I always get 0. What is the problem with this part of code?

Below is a program that generates random Addition for Subtraction problems depending on the user's choice. The user is prompted to input an answer and then it keeps your score. If you want to quit you just press zero.
Code:
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <iomanip>
#include <string>
using namespace std;
int menu();
bool addition(int &reward); // function to return truth values

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 !

I've to use recursion function that return if the string has a same letters:
for example: - fff = true
- fFf = false
I did this but the return answer is always: NOT!
bool iSameLetters(char str[SIZE]) {
if(str[0]=' ')
return true;
else {
if((str[0] && iSameLetters(str+1) == str[0]))
return iSameLetters(str+1);
return false;
}
}

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: ";

I'm working on a programming challenge and i need to uppercase all characters of the string.
string upperCaseIt(string& name){
for(int index = 0; index < name.length(); index++){
name[index] = toupper(name[index]);
return name;
}
}
My problem is that it only uppercase the first character of the string.

I have a problem. I need to print the string called "last" in uppercase format. can you check why my program prints nothing.
Here is the important section of the code.
if (infile.is_open()) // if file was able to open {
string line;
while (getline(infile, line)) {
string::size_type pos1 = line.find(' '); //pos1 is the position of the first space

I'm doing error checks in C and I'd like to know how to restrict the input of a string to 2 letters and if it is exceeded, i'd like to loop and ask for the code to be re-entered.
Code:
for (i = 0; i < code7; i++)
{
printf("Enter number of items: ");
scanf("%d", &item_qty[i]);

I am creating a program where I count all the letters of the alphabet from a user submitted string.
How would I go about this?
I am completely new, so simplicity is best. I am suppose to use arrays.

I'm having trouble trying to turn a word into letters. I've seen other posts but they deal with a sentence and it only outputs the words only. What I want to know is how do they take a word (Ex: "word") and break it into individual letters, where I want to store them in a vector of string?
If it's not too much trouble, I would prefer without using pointers or "std:: " marks, since I am trying to avoid pointers and I'm using "using namespace std" all the time.
Ex:
In the example "word", it should output into:
"w"
"o"
"r"
"d"
and I will push them back into a vector of string where each vector element contains a letter.

write a C program which repeatedly reads in sentences from the user and reports on how many capital letters are in the sentence and how many punctuation characters. Your program will stop asking for input once the user has entered in a blank line. Consider the following example usage with the program. User input is marked in underline:
Enter a sentence: John and Mary went to Fred's house.
You used 3 capital letters and 2 punctuation characters.
Enter a sentence: I like A&W more than McDonald's.
You used 5 capital letters and 3 punctuation characters.
Enter a sentence:
Good bye!
Hint: make use of the standard C functions ispunct and isupper. Other requirements. You must make two functions.
Make a function called find_characters, which has a return type of void, and which has three parameters: one of type char * (a string to find characters in), one of type int * (a reference to int variable indicating how many capital letters are in the string) and the last one also of type int * (a reference to an int variable indicating how many punctuation characters are in the string). Your find_characters function should scan the string and update the two variables it has references to.Make a main function.
This function should repeatedly read in a string from the user, call your find_characters function, and output the information returned to it by the find_characters function indicating how many capital letters and how many punctuation characters were in the string. Your main function should stop reading in input when the user enters in a blank string (i.e., the user just hits enter without entering anything else in). You may assume that the user will not enter in a sentence longer than 100 characters
Code:
#include<stdio.h>
#include<stdlib.h>
#include<ctype.h>
#include<string.h>
int main(void) {

how to convert a string containing Uppercase/Lowercase/Whitespace/Special Characters to only Lowercase and removing the whitespace and characters.
For example, a message like:
"The: sky is (blue), the wAter is also blue'."
Change that message to:
"theskyisbluethewaterisalsoblue"

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;
} }
