{
char s[100];
gets(s);
int i,length,n=0,ch=0;
length=strlen(s);
for(i=0;i<length;i++)
{
if(s[i]==0||s[i]==1||s[i]==2||s[i]==3||s[i]==4||s[i]==5||s[i]==6||s[i]==7||s[i]==8||s[i]==9)
{
n++;
} if(s[i]=='!'||s[i]=='@'||s[i]=='#'||s[i]=='

Answer 1

You could check it on the playground with some examples and see what happends.

Answer 2

Please refer to other threads on this subject. You have to check if there are two *different* special characters, not just *any* two.

Answer 3

#include<stdio.h>
#include<string.h>
int main()
{
char s[100];
scanf("%s",s);
int i,length,numbers=0,specialcharacter=0;
length=strlen(s);
for(i=0;s[i]!='\0';i++)
{
if(s[i]>='0'&& s[i]<='9')
{
numbers++;
}
else if(s[i]=='!'||s[i]=='@'||s[i]=='#'||s[i]=='#x27;||s[i]=='%'||s[i]=='&'||s[i]=='*')
{
specialcharacter++;
}
}
if((length>=7)&&(specialcharacter>=2)&&(numbers>=2))
{
printf("Strong");
}
else
{
printf("Weak");
}
return 0;
}
Hey guy's I solved it myself.Look the just some difference.
