i would like 2 thank u all in advance 4 ur time n help

#include <stdio.h>

int main(void)
{
    int nblivre, c;   
    float kg, cels, frnht;
    
    printf("Taper le poids en livres:\n");
    scanf("%d", &nblivre);
    
    printf("Taper la temperture en degres farenheit:\n");
    scanf("%f", &frnht);
    
    
    
    cels = ((frnht - 32) / 9) * 5;
    kg = 0.454 * nblivre;    
    
    printf("\nLe patient pese %.1f kg, a une temperature de %.1f degres", kg, cels);
     fflush(stdin);
    getchar();

    printf("Selectionnez votre status civile:");
     fflush(stdin);
    getchar();

     printf("\n\nAffichage avec switch (suivant que) :\n");
    
    
    switch (c)
    {
                    case 'c':
                         printf("celibataire.");
                         break;
                    case 'C': 
                         printf("celibataire.");
                         break;  
                    case 'a':
                         printf("un autre cas.");
                         break;
                    case 'A':
                         printf("un autre cas.");
                         break;
                    case 'm':
                         printf("marie.");
                         break;
                    case 'M':
                         printf("marie.");
                         break;
                    case 'd':
                         printf("divorce.");
                         break;
                    case 'D':   
                         printf("divorce."); 
                         break;
  
  printf("\n");
    fflush(stdin);
    getchar();
    return 0;   
}
}

believe my problem is located around the switch level, n i dont know how 2 use it 2 well, that is IF i used it well....tks 4 every1;s help

with the c>>> As far as I can tell, the variable c is never assigned a value. That may or may not be your problem.



how do i set it up as a value 4 letters...do i use char?


ty all for ur time n help

Don't flush stdin, it's naughty see, http://faq.cprogramming.com/cgi-bin/...&id=1043284351 for an alternative

Consider converting uppercase to lowercase in the switch, rather than repeating code.

#include <ctype.h>

/* ... */

switch(tolower(c))
{
    case 'c':
/* ... etc */

'c' isn't assigned a value, call

c = getchar();

program still crashes :S dont know y...when i want 2 do this part:

 printf("Selectionnez votre status civile:");
     fflush(stdin);
    getchar();

     printf("\n\nAffichage avec switch (suivant que) :\n");
    
    
    switch (c)
    {
                    case 'c':
                         printf("celibataire.");
                         break;
                    case 'C': 
                         printf("celibataire.");
                         break;  
                    case 'a':
                         printf("un autre cas.");
                         break;
                    case 'A':
                         printf("un autre cas.");
                         break;
                    case 'm':
                         printf("marie.");
                         break;
                    case 'M':
                         printf("marie.");
                         break;
                    case 'd':
                         printf("divorce.");
                         break;
                    case 'D':   
                         printf("divorce."); 
                         break;
  
  printf("\n");
    fflush(stdin);
    getchar();
    return 0;   
}
}

in dos mode it crashes..:S

You have defined 'c' as an integer, but you are trying to use it as a char. I doubt any of your switch statements are going to work that way. Change your definition of 'c' to char for starters. And nowhere do you assign the getchar() to c !!

its all good i got it workin tks alot

getchar() returns an int... it should be an int.

Just a little notice... there's another way of structuring your switch statement you might want to know..

switch (c)
{
                    case 'c':
                    case 'C':
                         printf("celibataire.");
                         break;
                    case 'a':
                    case 'A':
                         printf("un autre cas.");
                         break;
                    case 'm':
                    case 'M':
                         printf("marie.");
                         break;
                    case 'd':
                    case 'D':
                         printf("divorce.");
                         break;
}

or

switch (c)
{
                    case 'c':
                    case 'C':
                         printf("celibataire.");
                         break;
                    case 'm':
                    case 'M':
                         printf("marie.");
                         break;
                    case 'd':
                    case 'D':
                         printf("divorce.");
                         break;
                    default:
                        printf("un autre cas.");
                        break;
}

And yeah, the remarks of kcpilot about the int thing isn't right...
