Toggle Case in String – C Program
write a c program to convert upper case string to lower case string and lower case string to upper case string.
#include<stdio.h>
#include<conio.h>
void main()
{
char str[100];
int i;
clrscr();
printf("Please, Enter the String =");
//gets(str);
gets(str);
for(i=0;str[i]!=NULL;i++)
{
if(str[i]>='A'&&str[i]<='Z')
str[i]+=32;
else if(str[i]>='a'&&str[i]<='z')
str[i]-=32;
}
printf("\nThe toggle case string is = %s",str);
getch();
}
The output of toggle string program is:
Please, Enter the String = Meera Academy
The toggle case string is = mEERA aCADEMY
Why r we using conio.h
conio.h for clrscr() and getch() in turboC++ compiler.
