    array function(a tiny problem)

    i'm having trouble getting the right output: it should be 3LU$CH

    #include<iostream.h>
    #include<string.h>

    void main()
    {
    int index(char *,char);
    char line[30]="LUNCH";

    cout<<index(line, 'N')<<" "<<line<<endl;
    }



    this function will replace the 1st occurance of ch by a dollar sign and return teh posiiton where the occurrence is found. It returns a zero value if ch is not found.

    int index(char*s, char ch)
    {
    ******this is the part that needs to be done. I used the strncat function but it didnt work******
    }
    please provide some guidance and i'd b xtreemly grateful to you.thanx.

    1. Use the strchr function to find a char in a string.

    2. main returns an int
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
