Logic:-

This Problem Can Solve using ASCII Value .

String =String-32

After taking an input from the user we have to minus 32 in each character of a string so in this way we can convert the string lower case to upper case. This is why I already mention link above. For better practice, I strongly recommended to check and practice below post for the logic building if you are new in Programming.

#include<iostream>

using namespace std;

void upr(char*);

int main()
{
    char str[50];
    
    cout<<"=====================================";
    cout<<"\nVisit - www.nerdutella.com";
    cout<<"\n=====================================";
    
 cout<<"\n\nEnter a Lower Case String :";
    cin>>str;
    
 upr(str);
    
 cout<<"\n\nUpper Case String Is :"<<str<<endl<<endl; 
}
void upr(char *str)
{       
    int i=0;
    
    while(str[i]!='\0')
    {
        str[i] = str[i] - 32;
        i++;
    }  
}

 

Output:

=====================================

Visit - www.nerdutella.com

=====================================

Enter a Lower Case String :nerdutella

Upper Case String Is :NERDUTELLA
