    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;   
}
}

i 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

oh do i assign it ? do i use

const c

or


c = getche()
?

c is the status which is >>>>a,A,m,M,d,D,C,c

ok perfect will do and i m very sorry about that,

so can someone tell me why my dos page keeps closing down? i have made the necessary changes,

Code:

#include <stdio.h>

int main(void)
{
    int nblivre, c;   
    float kg, cels, frnht;
    
    printf("Taper le poids en livres:\n");
    scanf("&#37;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("Rentrer le statut civil:\n");
    c = getchar();
    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;
                         
  printf("\n");
    fflush(stdin);
    getchar();
    return 0;   
}
}

thanks alot for every1's help in advance

and what can i use instead of

Code:

fflush(stdin)

being very new i dont know what i can replace it by

i have 2 use dev-C++

and i will get ride of the fflush and getchar

i didnt....it was moved......from C++ 2 here...zacs7 my dos keep closing be4 it finishes exeecuting everything......and i dont seem 2 understand why


it crashes @ the switch(c)

ok so far this is the code

Code:

#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:");
   c = getchar();
   

    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");
 
    return 0;   
}
}

when i get 2

Code:

    printf("Selectionnez votre status civile:");

in dos mode i put in the letter "M" (for marie which is married) and Dos just quits
