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 ...
In this C++ tutorial, we will proceed to show exactly how one can convert an entire C++ String to uppercase, using the toupper() function.
At first we will implement the toUpper function. The purpose of this function is to convert all lowercase letters from a String to uppercase Letters.Example: 'aBc 3' becomes 'ABC 3'. It's important that letters like numbers or spaces won't be converted to anything different.#include <...
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)...
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 ...
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) ...
<< endl; } else { cout << "String is not in uppercase!" << endl; } } }; int main() { // create an object String S; // calling getString() function // to insert string S.getString(); // calling isUppercase() function // to check the string S.isUppercase(); return 0; ...
Cheers :) PS I have no idea whether/how your program goes in Thailand or Greece. You can chase that one up. Last edited on Jan 16, 2017 at 10:24pm Jan 16, 2017 at 4:50pm BlueSquirrelJQX (8) takaflaka, in fact, you can use the standard library function: islower(char ch) ...
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...
2. Usingstd::for_eachfunction If the boost library is not available, try using the standard algorithmstd::for_each, which applies a given function object to every character of the string. The function needs to convert a character to uppercasein-place, as shown below: ...
