Problem Statement - Output writing – Pointer to string as char array

Find and write the output of the following C++ program code:
Note : Assume all required header files are already included in the program.

 

void strpat(char *str)
{
  for(int i=0;str[i]>0;i++)
  {
    for(int j=0;j<=i;j++)
    {
      cout<<str[j];
    }
    cout<<endl;
  }   
}
int main( )
{
  char *t="CBSE";
  strpat(t);
  return 0;
}

 

Solution

TC++ #7709

Run Output 

C

CB

CBS

CBSE

void strpat(char *str) //Here the string CBSE will be passed as pointer to string from main()
{
for(int i=0;str[i]>0;i++) //This will run till null or numeric value 0 means till end of string as passed value is a null terminated string
{
for(int j=0;j<=i;j++) //This will traverse the string based on value of i
{
cout<<str[j]; //This will print C, CB, CBS, CBSE based on value of i from 0 to end of string
}
cout<<endl; //This will print a newline after each of loop of j
}
}
int main( )
{
char *t=”CBSE”; //Initialisation of a string as character pointing to its first ocation
strpat(t);              //character pointer is passed to function created above
return 0;
}

Notes

  • char *t=”CBSE”; //For this line warning or errors may come based on your compiler settings as string literal to char * conversion is not allowed in C++11 standard.
