Here is the program to convert a string to uppercase in C language, Example Live Demo #include <stdio.h> #include <string.h> int main() { char s[100]; int i; printf("\nEnter a string : "); gets(s); for (i = 0; s[i]!='\0'; i++) { if(s[i] >= 'a' && s[i...
Write a program in C program to convert a string to uppercase or lowercase using a callback function to modify each character. Sample Solution: C Code: #include<stdio.h>#include<ctype.h>voidmodify_string(char*str,int(*modifier)(int)){while(*str!='\0'){*str=modifier(*str);str++;}...
cout << "Original string: " << original_str << std::endl; std::cout << "Uppercase string: " << dest_str << std::endl; for(std::size_t i=0; i<std::size(original_str); ++i) { dest_str[i] = std::tolower(original_str[i]); } std::cout << "Original string: " <<...

printf("Uppercase string: %s\n",str); return0; } In the above code, we first declare a character array called str with a size of 100. The user’s string is then read using thefgets()method. Thestrupr()method is then used to transform the string to uppercase. Thestrupr()method rec...
调用方法:str.uppercaseString; str.lowercaseString; str.capitalizedString(实例名.属性名) 3、常用方法: - (NSString *)stringByAppendingFormat:(NSString *)format, ... 在字符串后面添加格式化字符串 - (NSString *)substringFromIndex:(NSUInteger)anIndex ...

这时,如果我们调用lowercaseString方法就会实际调用uppercaseString的方法,反之亦然。 然而!在实际应用中,只交换已经存在的两个方法是没有太大意义的。我们应该利用这个特性来给既有的方法添加新功能(听上去吊吊的): 它的实现原理是:先通过分类增加一个新方法,然后将这个新方法和要增加功能的旧方法替换(旧方法名 对...
