toupper

问题 I am creating a mailing label generator for school and am having an issue with a few problems. My program is to take the full name, address, city, state, and zip code for individuals from 0 to 10. When running my program I am having two major problems. The for loop skips the full name "safergets()" and moves on to the address safergets. I moved on to see if everything else works, but my verification for the zip code would not work correctly. I added a printf to see if the input was the same

问题 Say I have a string word. This string can change what characters it contains. e.g. word = "UPPER£CASe" How would I test the string to see if any character in the string is not uppercase. This string must only contain uppercase letters and no other punctuation, numbers, lowercase letters etc. 回答1: You should use str.isupper() and str.isalpha() function. Eg. is_all_uppercase = word.isupper() and word.isalpha() According to the docs: S.isupper() -> bool Return True if all cased characters in S

问题 #include <stdio.h> #include <ctype.h> char* strcaps(char* s) { while (*s != '\0') { toupper(*s); s++; } return s; } . int main() { char makeCap[100]; printf("Type what you want to capitalize: "); fgets(makeCap, 100, stdin); strcaps(makeCap); return 0; } this program compiles just fine, but when I run it, it doesn't output anything. what am i missing here? 回答1: You are not printing anything! Print the return value of toupper() . printf("%c",toupper(*s)); 回答2: You don't print anything, so of

问题 I'm searching a long time to find a method to convert a NON-LATIN String to upper and/or lowewr case. Cyrillic-, Greek- and co. Writing Systems. So in other words: Convert all characters that support upper/lower case to upper or lower. NOTE: QString from the Qt Framework supports this feature. But I'm searching for a non-Qt solution. I tried this piece of code, and it only supports Basic-Latin (a-z, A-Z) neither Á â ş Ş ȧ Ȧ etc. are supported. (???) Why so minimalistic? #include <iostream>

问题 I am wondering how the toupper() function in C works. I am trying it out in the code below but I'm definitely doing something wrong. The code compiles, but the arguments passed into toupper() are not being capitalized... char **copyArgs(int argc, char **argv) { char **a = malloc(sizeof(char *) * (argc)); int i; for(i = 0; i < argc; i++) { int size = strlen(argv[i]); a[i] = malloc(sizeof(char) * (size + 1)); strcpy(a[i], argv[i]); a[i] = toupper(a[i]); } return a; } If I test this with "one

问题 How to use topper and tolower in the C language? I've tried to run the program that I've made, it runs properly the problem is since I should submit it to a website to check it whether it's right or wrong, every time I submit it, it says compile error. I made the code on macbook, using Xcode and it says on my toupper and tolower code -- implicit declaration of function 'toupper' is invalid in C99 #include <stdio.h> #include <string.h> int main() { int input; scanf("%d",&input); int jumlahkata

问题 I have a collection of characters (',', '.', '/', '-', ' ') then I have a collection of strings (about 500). What I want to do as fast as possible is: after each of the characters I want to make the next letter uppercase. I want the first capitalized as well and many of the strings are all uppercase to begin with. EDIT: I modified tdragons answer to this final result: public static String CapitalizeAndStuff(string startingString) { startingString = startingString.ToLower(); char[] chars = new
