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
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 have a function that converts an integer to Roman numeral and i've been searching everywhere trying to find out how to convert an uppercase string to lower case but I haven't found a good answer anywhere.
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;
The problem I am facing is that I have to output the C++ input file and display every line of code in the output, except in the output I have to convert every if, else, and while as IF, ELSE, WHILE. I tackled the first part and now its onto the 'easier' part even t
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); }}
these function do the same of the sprintf() function. but instead we use a variable for add the result, i want to return the result. when i use it:
string f; f=ToString("hello world"); gives me several errors: "error: crosses initialization of 'std::string f'" "error: jump to case label [-fpermissive]"
In this code, i declared a string constant and trying to print the length of string. I know that if i write char a1[7] or char a1[] than it runs and give aggregate output, but in this case it is giving double length of string.
1. Create a variable named index and nitialize it to zero(0) 2. Prompt for and input a string value from thekeyboard. Store the string inthe string variable newstring[80]. 3. While (newstring[index] does not equal ‘ ’).
i. Display the character at newstring[index] followed by a NL ii. Increment index ====================================== ...
And this is what i have done so far and i dont know where I am wrong ...
Code: #include<stdio.h> int main() { int index = 0; //initialize index to zero since first elementin an array is numbered zero char newstring[80];
Here's what I have to do: Using strcpy() pass it two strings of characters (such as a name like John Johnson) and copy the second string into the first, in reverse order, and print both. Write a main to exercise your function and to illustrate that the function is working properly.
I try to learn string class, resolving some problem, but i have some dificulties.The is ok, but when i print the longest string it does'n print on the same line.I enter the number of string, after that i enter the first string until i introduced from keyboard "#" character. I enter the second string and so on.Look at these example :
For i = 3;
Text[0] : I learn class String# Text[1] : I dont learn class String# Text[2] : String#
It print me like that : Text[1] :
I dont learn class String More than that look at the next example :
For i = 3;
Text[0] : I learn class String#abcdef Text[1] : I dont learn class String# Text[2] : String#
You see that in the first sentence i have continue to introduce some characters after # character and look what is happened :
Text[1] : abcdef I dont learn class String
#include<iostream> #include<string> using namespace std; int main() { string text[100], cuvant; int i, j, m, lung = 0; cout << "
I'm trying to make a program in C where the user enters a string and it prints a word for example (name) in lowercase then the same word again but in capitals and lowercase like this (NnAaMmEe).
Given this sentence as an input: "Hello my name and "John" (with its spaces and capital letters), print it on the screen .. NB the phrase must be entered from the keyboard all at once ... you can do this in C / C + +?
