Question
Write the function first Not ln (). The function has two parameters; const char * str and const char * chars. The first is the C - style string to search, and the second is a C - style string containing characters to exclude. The function returns the index (as a size_t) of the first occurrence of any character from str that does not appear inside chars. If all of the characters inside str appear inside chars, return the value size_t (-1). You cannot use any library functions for this problem. You may use array or pointer notation.Explanation / Answer
#include<iostream>
using namespace std;
int firstNotIn(char *str, char *chars){
int ind1,ind2;
for(int i=0;i<30;i++){
if(str[i]==NULL){
ind1=i;
break;
}
}
for(int i=0;i<30;i++){
if(chars[i]==NULL){
ind2=i;
break;
}
}
cout<<"ind1 : "<<ind1<<" ind2: "<<ind2<<endl;
for(int i=0;i<ind1;i++){
for(int j=0;j<ind2;j++){
if(str[i]==chars[j])
return i;
}
}
return -1;
}
int main(){
char str[30];
char chars[30];
cout<<"Enter string : ";
cin>>str;
cout<<"Enter chars : ";
cin>>chars;
cout<<firstNotIn(str,chars);
return 0;
}
