    inputting data in a struct

    i have some problems inputting data in a struct


    Code:
    #include <stdio.h>
    
    #include <unistd.h>
    void input(patient *p, int nr, char cpr, char ankomst, char skade); 
    
    typedef struct patient 
    {
    	int nr;
    	char cpr[10];
    	char ankomst;
    	char skade;
    } patient;
    patient p[1000]; 
    int patientnr = 0;
    
    int main()
    {
    
            char tempCpr[10] = "02020202";
    	char tempAnkomst[1] =  "A"; 
    	char tempSkade[1] = "B"; 
    
    input(&p[patientnr], tempCpr, tempAnkomst, tempSkade);
    
    }
    
    void input(patient *p, int nr, char cpr, char ankomst, char skade)
    {
    	p->nr = nr;
    	p->cpr = cpr;
    	p->ankomst = ankomst2;
    	p->skade = skade;
    }

    forgot to add something.. read this code instead

    Code:
    #include <stdio.h>
    
    #include <unistd.h>
    void input(patient *p, int nr, char cpr, char ankomst, char skade); 
    
    typedef struct patient 
    {
    	int nr;
    	char cpr[10];
    	char ankomst;
    	char skade;
    } patient;
    patient p[1000]; 
    int patientnr = 0;
    void get(patient *p);
    
    int main()
    {
    
            char tempCpr[10] = "02020202";
    	char tempAnkomst[1] =  "A"; 
    	char tempSkade[1] = "B"; 
    
    input(&p[patientnr], tempCpr, tempAnkomst, tempSkade);
    get(&p[patientnr]);
    
    }
    
    void input(patient *p, int nr, char cpr, char ankomst, char skade)
    {
    	p->nr = nr;
    	p->cpr = cpr;
    	p->ankomst = ankomst2;
    	p->skade = skade;
    }
    
    void get(patient *p)
    {	
    	
    
    	
    	char cpr[10];
    	char ankomst3[1];
    	char skade2[1];
    	cpr = p->cpr;
    	ankomst3 = p->ankomst;
    	skade2 = p->skade;
    	
    	printf("\n %c\n", cpr);
    	printf("\n %c\n", ankomst3);
    	printf("\n %s\n", skade2);
    }

    it says incompatible types in assignment
    for these three lines
    cpr = p->cpr;
    ankomst3 = p->ankomst;
    skade2 = p->skade;

    there's an awful lot wrong with that code, including some really
    fundamental errors regarding use of strings and structs. i
    suggest that youstudy the tutorial and make sure you
    understand what you are doing before you try to write the
    complete program. i would scrap that code and start afresh
    instead, because trying to fix it will probably introduce more
    errors.

    No No's:
    fflush (stdin); gets (); void main ();

    well, i have seen this type code use by many people.
    Code:
    char tempAnkomst[1] =  "A"; 
    char tempSkade[1] = "B";
    why do u need a string to just store a one char. why cant u declare just a single char varibale. instead of declaring string and wasting the memeory and getting the error invalid assignmnet. the whole programe what u have done is just fine. rather than this part. i strongly recommand people not to use this type of method to just store a char. if this is method thought by the lecture just ignore it. instead use this

    Code:
    char tempAnkomst = 'A'; 
    char tempSkade = 'B';
    in your case raja. u have done it right in the skeleton of your struct. but atleast from that, u could have understood what the error is. your struct
    Code:
    int nr;
    char cpr[10];
    char ankomst;
    char skade;
    } patient;
    is the bolded code is string or a char. if its char how can u assign a char pointer to a charr.

    think about that.
