    C functions using loops

    can someone help me

    *Create a C program that will use the application of function in the program. The program will not accept 0 and above 20 as the number of inputs, the program will display "Invalid Input" when encounter these numbers. The program will ask again for a valid number of inputs.
    Sample I/O:
    Enter number of inputs: 3
    Num1: 1
    Num2: 2
    Num3: 4
    Sum is 7 and the product is 8
    Highest value is 4 and the lowest value is 1
    Repeat the process? [Press 1 for yes, other #s for exit]
    Note: You are asked to create a function prototypes and definitions for computing the sum, computing the product, finding the highest, and finding the lowest. The inputs should be done using a repetition statement

    Code:
    #include<stdio.h>
    #include<conio.h>
    #include<stdlib.h>
    
    
    int x , y, input;
    int sum(int x, int y);
    int prod(int x, int y);
    
    
    
    
    int main ()
    {
    int a, b;
    printf("Enter Number of inputs:\n");
    scanf("%d", &x);
    scanf("%d", &y);
    scanf("%d", &input);
    
    
    
    
    int add(int x,int y);
    int mult(int x,int y);
    
    
    printf("%d\n", add);
    printf("%d\n", mult);
    system("pause");
    return 0;
    }
    
    
    
    
    int sum(int x, int y)
    {
        return x + y;
    
    
    }
    
    
    
    
    
    
    int prod(int x, int y)
    {
        return x * y;
    }

    and here is for getting the largest and smallest number

    Code:
    #include <stdio.h>
    #include <conio.h>
    main()
    {
    int a[5],i,big,low;
    
    
    printf("Enter 5 Number\n\n");
    for(i=0;i<5;i++)
    scanf("%d",&a[i]);
    big=a[0];
    for(i=0;i<5;i++)
    {
    if(a[i]>big)
    big=a[i];
    else
    if(a[i]<low)
    low=a[i];
    }
    printf("\nLargest Number is=%d\nSmallest Number is=%d ",big,low);
    getch();
    }

    the question is if the user inputs any number the program will ask for the sum, product, the largest and the smallest number

    You don't ask anything, you just dubbed your exercise here. What is it that troubles you? Errors, Warnings, Crashes, Wrong results? If you can't tell me about your program what can I tell you?

    i almost got it but how can i insert the codes for getting the largest and smallest number?

    Code:
    #include<stdio.h>
    #include<conio.h>
    #include<stdlib.h>
    
    
    int add();
    int multiply();
    int hv=0;
    int lv=1;
    int exit();
    
    
    main()
    {
    int a, b, c, d,e,f;
    system("color F0");
    f=0;
    e=1;
    d=1;
    
    
    printf("Enter number of inputs: ");
    scanf("%d", &a);
    
    
    if((a>19)||(a==0))
    {
    printf("\nINVALID INPUT..");
    system("cls");
    getch();
    return main();
    }
    
    
    for(b=0; b<a; b++)
    {
    printf("\nEnter a number: ");
    scanf("%d", &c);
    f=f+c;
    e=e*c;
    }
    
    
    printf("\nThe sum is %d and the product is %d", f, e);
    printf("\n\nWant to try again? [1] Yes [other Digits] No: ");
    scanf("%d", &d);
    
    
    if(d==1){system("cls");return main();}
    if(d!=1){system("cls");exit();}
    
    
    getch();
    
    
    }
    
    
    int exit()
    {
    return 0;
    }

    Your min-max code is correct with a tiny mistake: set both "big" and "low" to "a[0]" at the beginning of your search loop. ( From post #7 )
