String Question 1

Question Asked in Companies like Sap labs , payu  etc  

Q.) You are given a string 'STR'. You have to convert the first alphabet of each word in a string to UPPER CASE.

For example:

If the given string 'STR' = ”I am a student of the third year” so you have to transform this string to ”I Am A Student Of The Third Year"

Note:

'STR' will contains only space and alphabets both uppercase and lowercase. The words will be separated by space.

Complete the function :

#include <bits/stdc++.h>

convertString(string str){

}

Here is the solution and Explanation :-

#include <bits/stdc++.h>
convertString(string str){
for(int i =0; i<str.length(); i++){
if( i ==0; || str [i-1] ==''){
str[i] = toupper(str[i]);
}
}
return str;
}

EXPLANATION :

#include<bits/stdc++.h> 

1) This includes all the standards library 

using namespace std;

string converString(string str)

2) This function takes a string single argument a string str and will return the string 

for(int i =0; str.length(); i++)

3)This for loop run and iterates over each character int he string the index 'i'.

if(i == 0 || str[i-1] == ' ')

4)  i == 0 check if current characters is  first character of the string 

    str[i-1]== ' '  this checks if previous character is a space , indicating the start of a new word 

    if condition is true it means current characrer is the first letter of a word 

5) str[i] = toupper(str[i]) this will convert the character to upper string 

6) return str; this will return the string
