File input cannot be read when running the program

[syakirin]

Hi, I would like to ask if there is any error in my code because I cannot read my input data when I run the program for read data from input file. Thank you

{
			ifstream StreamInput;
			StreamInput.open("InputData.txt");
	
			StreamInput >> ArraySize;
	                string name;
        		bool status=false;
        		cin.ignore();
        		cout<<"\nEnter name to search : ";
        		getline(cin,name);
        		for (int i=0;i<ArraySize;i++)
          		{
     
            		if (name == Student[i].Name)
              			{     
                		cout<<"\n**********Search Successful**********"<<endl;
                		cout<<"\nTest ID : "<<Student[i].Admission_Id <<"\t"<<"\t"<<"Phone Number : "<<Student[i].Phone_Number<<endl;
                		cout<<"\nName : "<<Student[i].Name<<endl;
                		cout<<"\nFather's Name : "<<Student[i].Father_Name<<endl;
                		cout<<"\nAddress : "<<Student[i].Address<<endl;
                		status=true;
            			}
                		break; 
              	        }         
                        if (status==false)           
                        cout<<"\n**********Search Unsuccessful**********"<<endl;
                        }

You should always check if the file opened correctly before to try to read or write to it.

#include <cstdio>
ifstream StreamInput("InputData.txt");
if (!StreamInput)
{
   perror("File error: ");
   exit(1);
}
