First I apologize for taking so much space. So this is my problem...
I am writing this little programm for a mock exam and i am supposed to create functions for bitwise operations (smth like a veeeeeery simple binary calculator). Anyway I used the fgets function within a while loop. Right after I call another function which is basicly a loop, and as far as I have understood the fgets reads somth byhereself and goes ino an infite loop.Here is the code (I have deleted the parts not interested...)
You can run it (It runs as itis) and see foryoureself.Code:#include <stdio.h> #include <stdlib.h> #define bit_len 24 void decimal(); void binary(); main() { int choice; printf("Will you use the binary(0) or the decimal(1) system: "); scanf("%1d",&choice); switch (choice) { case 0: binary(); break; case 1: decimal(); break; default: printf ("Min ise malakas, vale 1 i 0... ;-(\n\n"); break; } system("pause"); } void binary() { int i,check=0; char operand1[bit_len],operand2[bit_len]; char *ptr; do { printf("\n\nOperand No1(Up to 24 bits)\nRemember,only '0' and '1': "); fgets(operand1,sizeof(operand1),stdin); check=check_bin(operand1,check); } while(check!=1); printf("%d",check); } int check_bin(char *opr,int check) { while(*opr!='\0') { check=(*opr=='0')||(*opr=='1')?1:0; if (check=0) break; } return check; } void decimal() {}
If someone can help I would really appreciate it.
