I am having trouble identifying the flaws in my code. I need to created a program that calculates the rainfall for a given year in months. I needed it to show the total amount of rain for the year, the average monthly rainfall, and the months with the highest and lowest amounts. So far I got everything to calculate and display correctly all except the highest and lowest months. I have included the full code. Thanks.

#include<iostream>
using namespace std;

void main()
{
double rainfall[12], totalrainfall=0, avgrainfall =0, maximum =0, minimum=0;
int i,j,k,m,mimo, mamo;
char monthnames[12] = {'Jan','Feb','Mar','Apr','May','Jun','Ju…

for (i=0;i<12;i++)
{
cout<<"Enter rainfall for month "<<i+1<<":";
cin>>rainfall[i]; //capture all rainfall values from user
}

for(j=0;j<12;j++)
{
totalrainfall = totalrainfall + rainfall[j]; //calculate total rainfall
}

cout<<"Total rainfall for the year:"<<totalrainfall<<endl;

avgrainfall = totalrainfall/12; //calculate average rainfall
cout<<"Average monthly rainfall: "<<avgrainfall<<endl;

for(k=0;k<12;k++)
{
maximum = rainfall[0];
if (rainfall[k] > maximum)
{
maximum = rainfall[k]; //find maximum rainfall value
mamo = k; //month with max rainfall
}
}

for(i=k;i<=k;i++)
{cout<<"Maximum rainfall month: "<<monthnames[mamo]<<endl;}

for(m=0;m<12;m++)
{
minimum = rainfall[0];
if (rainfall[m] < minimum)
{
minimum = rainfall[m];
mimo = m;
}
}
for(i=m;i<=m;i++)
{cout<<"Minimum rainfall month: "<<monthnames[mimo]<<endl;}

}

Don't know which version of C++ you use.

In general, string≠char, but
char * points to a string with a '\0' termination character.

You could use the string class, for monthnames, or use an array of pointers, such as:
char *monthnames[]={"Jan","Feb",...};
depending on whether you are allowed to use pointers.

I have not compiled your program to see if there are other problems. If you find other problems, post.

There are a few flaws in your code that prevent it from correctly identifying the months with the highest and lowest amounts of rainfall:

1. First, the declaration of the array `char monthnames[12]` is not complete. The strings representing the month names should be enclosed in double quotes (`"`) instead of single quotes (`'`).

2. The initialization of the variables `maximum` and `minimum` inside the for loops is incorrect. You are setting them to `rainfall[0]` during each iteration, which means they will always be set to the first element of the `rainfall` array. Instead, you should initialize these variables before the loops start.

3. The code that prints the month with the maximum rainfall is placed inside an unnecessary loop. Since you already have the month index `mamo` with the maximum rainfall, you can directly access the corresponding month name from the `monthnames` array and print it without the loop.

4. Similarly, the code that prints the month with the minimum rainfall is also placed inside an unnecessary loop. You can directly access the corresponding month name from the `monthnames` array and print it.

Here's an updated version of your code with these flaws fixed:

```cpp
#include<iostream>
using namespace std;

int main()
{
double rainfall[12], totalrainfall = 0, avgrainfall = 0, maximum = 0, minimum = 0;
int mamo = 0, mimo = 0;
string monthnames[12] = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"};

for (int i = 0; i < 12; i++)
{
cout << "Enter rainfall for month " << i + 1 << ": ";
cin >> rainfall[i]; //capture all rainfall values from the user
}

for (int j = 0; j < 12; j++)
{
totalrainfall = totalrainfall + rainfall[j]; //calculate total rainfall
}

cout << "Total rainfall for the year: " << totalrainfall << endl;

avgrainfall = totalrainfall / 12; //calculate average rainfall
cout << "Average monthly rainfall: " << avgrainfall << endl;

maximum = rainfall[0];
for (int k = 0; k < 12; k++)
{
if (rainfall[k] > maximum)
{
maximum = rainfall[k]; //find maximum rainfall value
mamo = k; //month with max rainfall
}
}
cout << "Maximum rainfall month: " << monthnames[mamo] << endl;

minimum = rainfall[0];
for (int m = 0; m < 12; m++)
{
if (rainfall[m] < minimum)
{
minimum = rainfall[m];
mimo = m;
}
}
cout << "Minimum rainfall month: " << monthnames[mimo] << endl;

return 0;
}
```

With these changes, your code should correctly identify the months with the highest and lowest amounts of rainfall.
