I want to capitalize the days in the array named 'days' and get the result in an array form only by calling 'console.log(days)'
Please see below :Can anybody help me finish up code in the the block of for of loop?

edit(summary) : I questioned this to know the reason why the value of the each 'day' does not get changed in this case. and Suren Srapyan has provided a great answer to this :'You are getting the copy of each item in the loop. So day is only a copy of the item's value and changing it to have another value will not change the item in the array.'

let days = ['sunday', 'monday', 'tuesday', 'wednesday', 'thursday', 'friday', 'saturday'];for (day of days) {    day = day[0].toUpperCase() + day.slice(1);    // your code goes here}console.log(days);

    #include <stdio.h>    int main()    {        FILE *fp;        int i;        int pos;        fp=fopen("test.txt","r+");        fseek(fp,0,SEEK_END);        pos=ftell(fp);        char ch[pos-1];        fseek(fp,0,SEEK_SET);        ch[0]=ch[0]-32;        i=0;        while(ch[i]=fgetc(fp)!=EOF){            if(ch[i]!=' '){                fseek(fp,1,SEEK_CUR);                i++;            }            else{                fseek(fp,1,SEEK_CUR);                i++;                ch[i]=fgetc(fp);                ch[i]=ch[i]-32;                fprintf(fp,"%c",ch[i]);            }               }        fclose(fp);    }

I want to make C program that capitalizes the first characters of the words in the file. But when I run this code .txt file get wrong.Is usage of fgetc() wrong? where is my fault for this question ? And is fscanf moving cursor ?

Is there a function built into Java that capitalizes the first character of each word in a String, and does not affect the others?

Examples:

• jon skeet -> Jon Skeet
• miles o'Brien -> Miles O'Brien (B remains capital, this rules out Title Case)
• old mcdonald -> Old Mcdonald*

*(Old McDonald would be find too, but I don't expect it to be THAT smart.)

A quick look at the Java String Documentation reveals only toUpperCase() and toLowerCase(), which of course do not provide the desired behavior. Naturally, Google results are dominated by those two functions. It seems like a wheel that must have been invented already, so it couldn't hurt to ask so I can use it in the future.

What I would really like is to not have to hit the caps lock button as often as I do for a few key words. I know that many just use lower case only but all of the queries we write at the company I work for do this so it would be nice to not have to worry about it as much.

There are probably other issues that would arise from doing this but I kind of just want to give it a shot for a little while if I can. Thank you.

How do I make the first letter of a string uppercase, but not change the case of any of the other letters?

For example:

• "this is a test" -> "This is a test"
• "the Eiffel Tower" -> "The Eiffel Tower"
• "/index.html" -> "/index.html"
