Read in an integer N. Then read in N numbers and print their maximum and
second maximum (do not use arrays use loops) in c languange

What I have tried:

#include<stdio.h>

    int main(){
    
    int n,max,min;
    printf("Enter n: ");
    scanf("%d",&n);
    for(int i=1;i<=n;i++){
        scanf("%d",&i);
        if(n>max){
            n=max;
        }else{
            n=min;
        }
        printf("Max= %d\n",max);
        printf("min= %d\n",min);
    }
    
    return 0;
}

Do the print after the loop. (not in it)

3 solutions

Solution 1

if you use the debugger you may have seen the missing if and buggy assigment.

C++

if(n>max){
    n=max;
}else if(n<min){
    min=n;
}

Solution 3

// find maximun and minimun in n numbers
#include<stdio.h>

    int main(){
    
    int a,min=5,max=0,i=0,n;
    printf("Enter n: ");
      scanf("%d",&n);

   for(i=0; i<n; i++){
       printf("enter the numbers: ");
      scanf("%d",&a);
   }
       if (a > max){ 
           max=a; 
       }
        else if(a < min) {
           min=a; 
       }
        printf("max=%d\n",max);
        printf("min=%d\n",min);
    
    return 0;
}

I'd strongly suggest two things:
1) Check your code with this set of numbers: {-6, -5, -3}
2) Read your homework question again carefully: pay attention to the bit which talks about print the "minimum" ... look closely at the specific wording.

Solution 2

This is homework, so I'll give you no code.

Create two variables : max1 and max2.
Set both of them to the minimum possible value: if you include the LIMITS.H header file, you will find it is defined as INT_MIN.
Inside your loop, compare the current value to max1. If it's greater, then set max2 to max1 and set max1 to the current value
Otherwise, compare the current value and max2. If it's greater, then set max2 to teh current value.
After the loop, you have the two biggest values in max1 and max2

no it is not a homework, I a beginner just practicing some ques, can you send code, not able to solve properly!

OriginalGriff 25-May-21 6:50am

And what would that achieve?
You are a beginner, so what - exactly - would you learn from my writing code?
Would you learn how to do it yourself? Probably not.

Give it a try: this is a pretty simple exercise!

what is this header file LIMITS.H? I have tried this but result not coming!
