48. Write a function that will scan a character string passed as an argument and convert all lowercase characters into their uppercase equivalents
#include<stdio.h> ( this applies in the given code )
#include
void UpperCase(char *);
int main(void)
{
char str[50];
printf(“Enter String : “);
scanf(“%s”,str);
UpperCase(str);
printf(“String in Upper Case : %s”,str);
return 0;
}
void UpperCase(char *ch)
{
int i=0;
while(ch[i]!=’\0′)
{
if(ch[i]>=’a’ && ch[i]<='z')
{
ch[i]=ch[i]-32;
}
i++;
}
}
OUTPUT
Enter String : king
String in Upper Case : KING
