In this C++ tutorial, we will proceed to show exactly how one can convert an entire C++ String to uppercase, using the toupper() function.
The C++ std::ios::uppercase() function is used to modify the behaviour of stream output operations. When it is invoked, it makes the characters to be displayed in uppercase. This manipulator is used with the output streams to ensure that the numeric values are printed in uppercase ...
2. Using std::for_each functionIf the boost library is not available, try using the standard algorithm std::for_each, which applies a given function object to every character of the string. The function needs to convert a character to uppercase in-place, as shown below:...
operate onstd::stringcharacters range and convert eachcharto uppercase letters using thetoupperfunction. Notice that, even though this method successfully transforms the single-byte characters from the given string, characters with multi-byte encoding don’t get capitalized, as seen in the program ...
0x2a with uppercase: 0X2A 0x2a with nouppercase: 0x2a 1e-10 with uppercase: 1E-10 1e-10 with nouppercase: 1e-10 See also resetiosflags clears the specified ios_base flags (function) setiosflags sets the specifiedios_baseflags (function)...
C++ code to check if the string is in uppercase using the class and object approach #include <iostream>usingnamespacestd;// create a classclassString{// private data memberprivate:charstr[30];// public member functionspublic:// getString() function to store stringvoidgetString() { cout<<...
#include <bits/stdc++.h> // Include all standard libraries using namespace std; // Using the standard namespace // Function to check if the string is all uppercase or all lowercase string test(string text) { for (int i = 1; i < text.size(); i++) { // Loop through the ...
In the main() function, we are creating an object S of class String, reading a string by the user using the function getString(), and finally calling the upperercase() member function to change the case from lowercase to the uppercase of the given string. The uppercase() function ...
Output: 0x2a with uppercase: 0X2A 0x2a with nouppercase: 0x2a 1e-10 with uppercase: 1E-10 1e-10 with nouppercase: 1e-10 See also resetiosflags clears the specified ios_base flags (function) setiosflags sets the specified ios_base flags (function) ...
Edit & run on cpp.sh Mar 20, 2015 at 5:47am TarikNeaj(2580) Well. It never enters the loop while(arrayIN[256] !='\n');What are you trying to do here? Also another big problem. in the function changeCase, you change to whatever, but then you want to print out the change wh...
