Program gets terminated abruptly in Visual C++ -

whwenever try execute block of code abruptly shuts down if dont use getch() function. have tried different combinations of accepting , printing string gets() , puts() etc. question causes error , how can remove error?

void main() {   char str[100];   printf("enter string\n");   fgets(str,100,stdin);   printf("%s",str);   getch(); } 

void main() {   char str[100];   printf("enter string\n");   fgets(str,100,stdin);   printf("%s",str);   getch(); } 

you have many problems small program.

1. you using getch(); requires #include <conio.h>
2. you using printf() family functions. requires #include <stdio.h>
3. the function prototype main() has int main(void) in case

in conclusion, fixed code:

#include <stdio.h> #include <conio.h> int main(void) {   char str[100];   printf("enter string\n");   fgets(str,100,stdin);   printf("%s",str);   getch();   return 0; } 

run cmd.exe command line window.

the reason shuts down because after completing in program, program automatically terminates. getch() makes system wait input.
