Hi Md Nayeem, Sorry, actually I didn't check my output. Please remove max and min from for loop, initialize it with first element of an array before loop. Please have a look into this screenshot, you will find your all answer :- #include #include using namespace std; int main() { ifstream f( "hello.txt" ); int num,i=0,max,min,sum=0; int arr[10]; while (!f.eof()){ f>>num; arr[i]=num; i++; } max=arr[0]; //assume first number is the maximum number; min=arr[0]; //assume first number is the minimum number; cout "File data :- " ; for (i=0;i cout "	" if (max //to find max number max=arr[i]; if (min>arr[i]) //// to find min number min=arr[i]; sum=sum+arr[i]; } cout "

Maximum number :- " cout "

Minimum number :- " cout "

Sum of all number :- " return 0; }

#include using namespace std; int main() { int i, n; int sum=0; float arr[100]; cout "Enter total number of elements(1 to 100): " ; cin >> n; cout // Store number entered by the user for (i = 0; i { cout "Enter Number " " : " ; cin >> arr[i]; } // Loop to store largest number to arr[0] for (i = 1;i { // Change if you want to find the smallest element if (arr[0] arr[0] = arr[i]; } cout "Largest element = " for (i = 1;i { // Change if you want to find the smallest element if (arr[0] > arr[i]) arr[0] = arr[i]; } cout "Smallest element = " for (i=0;i { sum=sum+arr[i]; } cout "Sum of All elements = " return 0; }

Mahesh Verma in your program you took input as 12 23 44 55 36 47 58 29 10 15 in hello.txt but in the output you show maximum number 15 as maximum number but in this case maximum number is 58.So how can i solve this program error.Thanks in advance .

#include using namespace std; int main() { int n, reversedNumber = 0, remainder; cout "Enter an integer: " ; cin >> n; while (n != 0) { remainder = n%10; reversedNumber = reversedNumber*10 + remainder; n /= 10; } cout "Reversed Number = " return 0; } Enter an integer: 12345 Reversed number = 54321

#include #include using namespace std; int main() { ifstream f( "hello.txt" ); int num,i=0,max,min,sum=0; int arr[10]={0}; while (!f.eof()){ f>>num; //read data from file arr[i]=num; //store into an array i++; } for (i=0;i max=arr[0]; //assume first number is the max number; min=arr[0]; //assume first number is the min number; if (max //to find max number max=arr[i]; if (min>arr[i]) // to find min number min=arr[i]; sum=sum+arr[i]; //sum of all elements of a file } cout "
 Maximum number :- " cout "
 Minimum number :- " cout "
Sum of all number :- " return 0; } In my "hello.txt" file the data is :- 12 23 44 55 36 47 58 29 10 15 Now, output is :-
