Function 2 Help Please!

2. Write a program with two functions. In main ask for a number. Pass this to the first function and print the value. In the first function ask for a character. Pass the first number and the character to the second function. In the second function print the number entered in main and the character entered in the first function. Back in main print "That's the end of this lab".

Code:

---

Code:

---

#include<stdio.h>
void fun (float); /* the FUNCTION PROTOTYPE  */       
main()
{
        float a;
        printf("Please enter a number: "); /* Program in MAIN */
        scanf("%f",&a);
        fun(a);
    getch();
}


void fun (float x) /* Function Header/Definition –  NO semicolon  */
{
        char q;
    printf("The number you entered is %4.2f.",x);
        printf("\n\nPlease enter a character: ");
        scanf("%c",q);
        return(0); /* value of product is returned to the main function */
}

Can you Please help to send from one function to another? Please!

Thank You So Much!

You have already successfully passed a value from one function to another (from main() to fun()). So why do you have a problem doing it again? The only difference is that instead of one value you have to pass two values to the second function.

Bye, Andreas

Even more so, you have a call to scanf being passed two parameters already, so it's not like there is some mysterious notation that you don't know how to use.

haha - nice copy and paste job mate, I think the 'learning lab' comments give it away a bit too

My guess is because the OP does not understand the code they had as example guide. Call me a cynic maybe.

Code:

---

#include<stdio.h>
void fun (float); /* the FUNCTION PROTOTYPE  */       
void fun2 (char , float);
main()
{
        float a;
        printf("Please enter a number: "); /* Program in MAIN */
        scanf("%f",&a);
        fun(a);
        printf("\nBack in main.");
        printf("\n\nThat 's the end of this lab.");
    getchar();
  }


void fun (float x ) /* Function Header/Definition –  NO semicolon  */
{
        char c;
        printf("\nFirst function");
    printf("\n\nThe number you entered is %4.2f.",x);
        printf("\n\nPlease enter a character:  ");
        scanf("%c",&c);
        getch();
        fun2(c,x);
        return(0); /* value of product is returned to the main function */
}


void fun2(char c , float x)
{
       
        printf("\n\nSecond function.");
        printf("The numer  you entered is %4.2f.",x);
        printf("\n\nThe character you have entered is %c",c);
        getch();
        return(0);
}

You have to tell us what's wrong with your program.

I guess that your program skips the line where you try to get the character input. The problem is that there is still a newline charater in the input buffer after you have entered the float number. Use

Code:

---

scanf(" %c", &c); // note the leading space before %

Bye, Andreas

He loses the char from the first function, so it won't print in the second one, also.

Code:

---

#include<stdio.h>

void fun (char *,float); /* the FUNCTION PROTOTYPE  */
void fun2 (char, float);
int main(void)
{
    float a;
    char c;
    printf("Please enter a number: "); /* Program in MAIN */
    scanf("%f",&a);
    fun(&c,a);
    printf("\nBack in main.");
    printf("\n\nThat 's the end of this lab.");
    getchar();

  return 0;
}
 
 
void fun (char *c,float x ) /* Function Header/Definition –  NO semicolon  */
{
    printf("\nFirst function");
    printf("\n\nThe number you entered is %4.2f.",x);
    printf("\n\nPlease enter a character:  ");
    scanf(" %c",c);
    getchar();
    fun2(*c,x);
}
 
 
void fun2(char c, float x)
{
   
    printf("\n\nSecond function.");
    printf("The numer  you entered is %4.2f.",x);
    printf("\n\nThe character you have entered is %c",c);
    getchar();
}

That's one way.
