25 pts) Level 1 Programming Task Write the function getPop(char myCode[3]), which takes in a two-digit string representing the state or territory code and returns the associated state or territory population. The function should open and scan the file USpops. txt for the input two-digit code, myCode. If myCode is not found in the file, the function should return -1. Make sure to close the file once the file reading is complete.

The method definition to this question can be defined as follows:

int getPop(char myCode[3])//defining a method getPop that takes char array in its parameter

{

FILE* f = NULL;//defining a pointer variable

int pop;//defining integer variable

char s_code[2];//defining char array state_code

char s_name[100];//defining char array stateName

f = fopen("state", "r");//using pointer variable that use fopen method for open file

if(f == NULL)//defining if block that check file is empty

{

return -1;//return value -1

}

while(!feof(f))//defining while loop for input value in file

{

fscanf(f, "%s %s %d",s_code, s_name, &pop);//input value

if(strncmp(myCode, s_code, 2) == 0)//use if block to compare string value

{

printf("Population for %s: %d", s_name, pop);//print value

return 0;//return 0

}

}

fclose(f);//close file

return 0;

}

Explanation:

In the above code, a method "getPop" is defined that accepts a character array "myCode" in its parameter, and inside the method, one pointer variable "f", one integer variable "pop", and two char array "s_code and s_name" is declared.

In the method firstly fopen method is used that holds a file and use if block to check it is not empty, if the condition is true it will give a value that is "-1".

In the next step, a while loop is declared, that input value and use if block to compare string value, and return 0, and at the last, it closed the file.    

the answer is d.
