dear sir
I want to write a program for printing “Hello World” & then ask for reprinting in y/n. if answer “c” is
c!= ‘y’ or ‘Y’ or ‘n’ or ‘N’ then it ask Enter the correct decision
‘n’ or ‘N’ then exit from loop
‘y’ or ‘Y’ then again printing “Hellow World” & then again repeat
I write my program as given below. in this problem highlighted while loop " while((c!=‘n’||c!=‘N’)||(c!=‘Y’||c!=‘y’))" is not working properly.
in this loop if I enter c=n or y then this loop is executed rather than get out from the loop which should be wrong. kindly tell me in this while loop where I did a mistake?
#include <stdio.h>
int main()
{
char c;
int x[100];
do{
printf(“hello world\n”);
printf(“r u want to continue y/n=”);
scanf(" %c",&c);
if(c==‘n’||c==‘N’)
break;
while((c!=‘n’||c!=‘N’)||(c!=‘Y’||c!=‘y’))
{
printf("\nEnter the correct decission=");
scanf(" %c",&c);
}
if(c==‘n’||c==‘N’)
break;
}
while(c==‘Y’||c==‘y’);
return 0;
}
