Thread: fgets problem

I try to store a sentences in key.programme using fgets but it never work. It just scan the first word just like a scanf. It dont scan a whitespace. Please help. TY

Code:

#include <stdio.h>
#include <stdlib.h>

struct record{
    char* name;
	char* programme;
	int id;
	float cgpa;
};

typedef struct record record;

int main(){

	record key;

	printf("Programme:");
	fflush(stdin);
	fgets(key.programme, sizeof(key.programme),stdin);
	printf("Input received: %s", key.programme);
}

You need to allocate memory for the string ex. in your struct make it an array of 255

what if i dont want to. I just wanted to use char* ? is it legal?

Code:

#include <stdio.h>
#include <stdlib.h>

struct record{
    char name[20];
	char programme[20];
	int id;
	float cgpa;
};

typedef struct record record;

int main(){

	record key[1];

	printf("Programme:");
	fflush(stdin);
	fgets(key[0].programme, sizeof(key[0].programme),stdin);
	printf("Input received: %s", key[0].programme);
    key[1].programme = "hello world";
	printf("Input received: %s", key[1].programme);
}

I try to assign a sentences in it but it always say it's type is unmatch. What should I do?

Key[1].programme doesnt exist, you can only index key[0], also line 21 you can not directly assign a string like that, you must use strcpy in the string.h library

Still no hope. incompatible types when assigning to type 'char[20]' from type 'char *'

Code:

#include <stdio.h>
#include <stdlib.h>

struct record{
    char name[20];
	char programme[20];
	int id;
	float cgpa;
};

typedef struct record record;

int main(){

	record key[1];

    key[0].programme = "hello world";
	printf("Input received: %s", key[0].programme);
}

Line 17 you can not assign directly try including string.h library and doing something along these lines

strcpy(key[0].programme,"hello world");

oh it works. Why we can't directly assign "Hello World" in it? Char* seems working well on this.

oo ok thanks. get it. lesson learn.
