corrected:

Returns an integral value indicating the relationship
between the strings:
A zero value indicates that both strings are equal.
A value greater than zero indicates that the first character
that does not match has a greater value in str1 than in
str2; And a value less than zero indicates the opposite.

int compare(char str1[], char str2[]) {
int flag = -1;
int i=0;
while(str1[i]!='\0' && str2[i]!='\0'){
if((str1[i]==str2[i])) {flag = 0;}
else if (str1[i]>str2[i]) {
flag=1;
break;
}else if(str1[i]<str2[i]){
flag = -1;
break;
}
i++;
}

if(strlen(str1)==strlen(str2) && flag==0 ){
flag = 0;
}
else if(strlen(str1)>strlen(str2) && flag==0 ){
flag = 1;
}
else if(strlen(str1)<strlen(str2) && flag==0 ){flag = -1;}
return flag;

}

I need a help with a program: Write a C program that uses data input in determining the whole of points A and a whole of circles B. Find two points in A so that the line which passes through them, cut through the maximum number of circles.
