holes = 0;
char word[100];
printf(“please enter the number of test cases\n”);
scanf("%d",&test);
while(test–)
{
scanf("%s",&word);
length = strlen(word);
for(i=0;i<length;i++){
if(word[i]==‘A’ || word[i]==‘D’ || word[i]==‘O’ || word[i]==‘P’ || word[i]==‘Q’ ||word[i]==‘R’ )
{
holes+=1;
}
else if(word[i]==‘B’)
{
holes+=2;
}
}
printf("%d \n",holes);
holes=0;

#include<bits/stdc++.h>
using namespace std;
int main()
{
int t,c,i;
string s;
cin>>t;
while(t–)
{
cin>>s;
c=0;
for(i=0;i<s.size();i++)
{
if((s[i]==‘A’)||(s[i]==‘D’)||(s[i]==‘O’)||(s[i]==‘P’)||(s[i]==‘Q’)||(s[i]==‘R’))
c++;
else if(s[i]==‘B’)
c+=2;
}
cout<<c<<endl;
}
}

IS MY CODE GETTING RUNTIME ERROR CAN U SOLVE

{
c++;
}
else if(s[i]==‘B’)
{
c=c+2;
}
}

  cout<<c;
}

}

Your code will produce WA for 2 two reasons. You are not making c=0 for every input and the 2nd thing is, you are not checking for s[i]==‘O’. I have debugged your code. Check it here https://ideone.com/Nhgdqs

27

still with the same code run time error is comming…

28

for the same code there is error

29

Nop! It is working correctly! :\ What are you talking about? And another thing. Take char s[101].

code having run time error

ok check

this link…

32

yes,thanx a lot answer came with s[101].
can u explain the reason of using s[101]. :slight_smile:

33

Because it is given in the problem statement that ‘The length of the text is less then 100’. Your previous code was trying to access an element of the string which is out of it’s range.

thanx for your help…
as i have successfully compiled my first program on codechef.
