Structs

[gilly]

Hi,

I'm trying to search the inputed data, using a second struct and printing the result if the two names match.
Eg i have entered
Joe BROWN 10/10/1000
Chris BROWN 10/10/1000
Joe BROWN 10/10/1000
Matt Brown 10/10/1000

then i enter JOE in the search string, and wish to scan the original struct for all joe's. However i have no idea how to do this, please if anyone could inform me on how to do this it would be great.

Below is the code i have already written:


//
//
//
#include <stdio.h>
#include <string.h>
#include <assert.h>

#define TRUE 1
#define FALSE 0

#define MAX_NAME_LEN 20
#define MAX_STUDENTS 21

typedef struct student Student;
struct student {
char first_name [MAX_NAME_LEN];
char last_name [MAX_NAME_LEN];
int birthyear;
int birthmonth;
int birthday;

};

typedef struct student1 Student1;
struct student1 {
char string_name [MAX_NAME_LEN];
};



int main (int argc, char **argv) {

int i = 0;
int j = 0;
int p = 0;
int keepReading = 1;

Student students [MAX_STUDENTS];
Student1 student1s [MAX_STUDENTS];



while (keepReading == TRUE && i < MAX_STUDENTS) {
if (keepReading == TRUE) {
printf ("Please enter your first name\n");

if (scanf ("%20s", students[i].first_name) == EOF) {
keepReading = FALSE;
}
}

if (keepReading == TRUE) {
printf("please enter your last name\n");

if (scanf ("%20s", students[i].last_name) == EOF) {
keepReading = FALSE;
}
}
if (keepReading == TRUE) {
printf("Please enter the day of your birth\n");

if (scanf ("%d", &students[i].birthday) == EOF) {
keepReading = FALSE;
}
}
if (keepReading == TRUE) {
printf("Please enter the month of your birth\n");

if (scanf ("%d", &students[i].birthmonth) == EOF) {
keepReading = FALSE;
}
}
if (keepReading == TRUE) {
printf("Please enter the year of your birth\n");

if (scanf ("%d", &students[i].birthyear) == EOF) {
keepReading = FALSE;
}
}

i++;
}

while(j < i - 1) {
printf("%s %s, was born on %d/%d/%d\n", students[j].first_name,students[j].last_name, students[j].birthday,students[j].birthmonth,students[j].birthyear);
j++;
}

int keepReading2 = 1;

while(keepReading2 == TRUE && p<21){

printf("Enter search string\n");

if (scanf ("%20s", student1s[p].string_name) == EOF) {
keepReading2 = FALSE;
}

p++;

}



return (0);
}


Advanced Thanks

Do you mean when you enter JOE,joe,JOe...etc., you want the program should find the "joe" struct???

Therefore you can convert the input to lowercase, iterate over the struct array
and use strcmp(); if the input and the struct's name attribute is equal or not...
