for loop ignoring scanf inside loop

Logicially I think it's possible to have a scanf in a for loop. Am I wrong?

Here is the code that's ignoring the loop, I took out the parts that are not required to answer this question. When running the program choose 1 and then a number, between 3-10 should be sufficent:

Code:

---

int main()
{ // open main
    int selection, amount, count;
    int value;
    printf("Welcome to the Cacluator of Statics of Materials\n\n");
    printf("1.  2-D Resultant Force at a point.\n");
    printf("Please choose a selection: ");
    scanf("%d", &selection);
   
    if(selection == 1)
        {
        printf("\nYou choose to calcualte a Resultan Force at a point.\n\n");
        printf("Please insert the amount of Forces: ");
        scanf("%d", &amount);
        int forces[amount];
        count = 0;;
        for(count == 0; count < amount; count++)
        {
        printf("\nPlease insert the value of force #%d: ", count+1);
        scanf("d", &value); // <---- This is being ignored why?
        forces[count] = value;   
        }
        }
        else
        {
        printf("\nSelection Invalid!  Please re-run the program.\n\n");
        } 
 system("PAUSE"); 
} // close main

You have several mistakes in your code:

Code:

---

int main()
{ // open main
    int selection, amount, count;
    int value;
    printf("Welcome to the Cacluator of Statics of Materials\n\n");
    printf("1.  2-D Resultant Force at a point.\n");
    printf("Please choose a selection: ");
    scanf("%d", &selection);
   
    if(selection == 1)
        {
        printf("\nYou choose to calcualte a Resultan Force at a point.\n\n");
        printf("Please insert the amount of Forces: ");
        scanf("%d", &amount);
        int forces[amount];
        count = 0;; //<--- two ; here
        for(count == 0; count < amount; count++)
        {
        printf("\nPlease insert the value of force #%d: ", count+1);
        scanf("d", &value);
        forces[count] = value;   
        }
        }
        else
        {
        printf("\nSelection Invalid!  Please re-run the program.\n\n");
        } 
 system("PAUSE"); 
} // close main

First, modify "d" into "%d" inside the scanf(), change the equality check "==" into an assignment "=", then try again.

That's a sign I need to go to sleep. Thank you... all I was missing was the %.

As for the "==" I declared count = 0; therefor i'm saying that when count is equal to 0 run the loop. May not be the best way but it works.

the ;; got there by deleting code to post on here. Wasn't in the main program, thank you for notifying me though.
