Use Bash please

Using only the standard input/output function fgetc(), define a C function, called int readInt(int *value), that reads an integer from the keyboard (stdin), stores it in *value and, returns 1 for success or 0 for fail (in case the user enters nondigit characters). In particular, readInt() reads all characters, one by one, until a blank (or newline) is encountered. The string is then converted to an integer. It is also possible to have the sign charcater (+/-) precedding the number.

Notes:

You need also to define a main() function that should look like the following one:

int main(int argc, char *argv[]){

:

:

printf("Enter a first integer> ");

if (readInt(&n1))

printf("You enetered %d ", n1);

else

printf("Wrong input ");

printf("Enter a secnd integer> ");

if (readInt(&n2))

printf("You enetered %d ", n2);

else

printf("Wrong input ");

printf("the sum of %d and %d is %d ", n1, n2, n1+n2);

exit(0);

}

Do not use any other function from the input/output standard library, and the string-to-integer conversion should be done using ASCII codes and multiplcations by 10.
