    Question Program to find the largest and lowest value

    I am trying to write a C program that can accept 10 numbers between 1 and 100. If values outside the range are entered an error message should be displayed and allow the user to enter a correct value. It should then find the highest value entered and lowest value entered.

    Here is what i have tried so far but i get the output "All numbers must be between 1 to 100". Kindly assist.

    Here is my code:

    Code:
    #include "stdio.h"
    
    
    int main() {
       int num1, num2, num3, num4, num5, num6, num7, num8, num9, num10;
     
       printf("\nEnter the first number : ");
       scanf("%d", &num1);
     
       printf("\nEnter the second number : ");
       scanf("%d", &num2);
       
          printf("\nEnter the third number : ");
       scanf("%d", &num3);
     
       printf("\nEnter the fourth number : ");
       scanf("%d", &num4);
      
       printf("\nEnter the fifth number : ");
       scanf("%d", &num5);
     
       printf("\nEnter the sixth number : ");
       scanf("%d", &num6);
       
          printf("\nEnter the seventh number : ");
       scanf("%d", &num7);
     
       printf("\nEnter the eighth number : ");
       scanf("%d", &num8);
          
          printf("\nEnter the nineth number : ");
       scanf("%d", &num9);
     
       printf("\nEnter the tenth number : ");
       scanf("%d", &num10);
       
       if ((num1 < 1 &&  num2 < 1 &&  num3 < 1 &&  num4 < 1 &&  num5 < 1 &&  num6 < 1 &&  num7 < 1 &&  num8 < 1 &&  num9 < 1 &&  num10 < 1) &&
       (num1 > 100 &&  num2 > 100 &&  num3 > 100 &&  num4 > 100 &&  num5 > 100 &&  num6 > 100 &&  num7 > 100 &&  num8 > 100 &&  num9 > 100 &&  num10 > 100)){
           
           if( num1>=num2 && num1>=num3 && num1>=num3 && num1>=num4 && num1>=num5 && num1>=num6 && num1>=num7 && num1>=num8 && num1>=num9 && num1>=num10)
           printf("%d.2lf is the largest number.", num1);

           printf("%d.2lf is the smallest number.", num1);
           
           else if( num2>=num1 && num2>=num3 && num2>=num3 && num2>=num4 && num2>=num5 && num2>=num6 && num2>=num7 && num2>=num8 && num2>=num9 && num2>=num10)

    Start with

    int num[10];

    Then replace your copy/paste of input with
    Code:
    for ( i = 0 ; i < 10 ; i++ ) {
       printf("\nEnter the %d number : ",i+1);
       scanf("%d", num[i]);
    }
    You can then do a similar loop to find min/max within the array.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Can you explain a little more ?

    Code:
    #include <stdio.h>
    int main()
    {
    	int i, sayi[5], max = 0;
    
    
    	for(i = 0; i < 5; i++)
    	{
    		printf("Lutfen %d. sayiyi girin.\n", i);
    		scanf("%d", &sayi[i]);
    
    
    		if(sayi[i] >= max)
    		{
    			max = sayi[i];
    		}
    		else
    		{
    			max = max;
    		}
    	}
    printf("max sayi : %d\n", max);
    
    
    	return 0;
    }
