char - Why is my C function returning the incorrect int? -

i'm making simple program asks user minimum , maximum values (between 32 , 127, inclusive), reason every time try store minimum value gets replaced value.

here code:

#include <stdlib.h> #include <stdio.h> #define lenlimit 256  char text[lenlimit];  int enternumber(int lolimit, int hilimit) {     printf("please enter integer between 32 , 127: ");     fgets(text, lenlimit, stdin);     int enter = atoi(text);     int exit;     if (enter < 32 || enter > 127) {         printf("min %i out of range\n", enter);         enternumber(enter, hilimit);     }     if (enter >= 32 && enter <= 127 && hilimit > 127) {         exit = atoi(text);         printf("min %i in range\n", exit);     }     if (lolimit >= 32 && lolimit <= 127 && hilimit <= 127 && enter >= lolimit) {         exit = hilimit;         printf("max %i in range\n", exit);     }     printf("num returned: %i\n", exit); //prints twice, why?     return exit; }  void printtable(int lolimit, int hilimit) {     (int = lolimit; <= hilimit; i++) {         printf("ascii character%3d %c.\n", i, i);     } }  int main(int argc, char* argv[]) {     int min = enternumber(31,128);     printf("min: %i\n", min);     int max = enternumber(min, 128);     printf("max: %i\n", max);     printtable(min, max);     return(exit_success); } 

and here result:

please enter integer between 32 , 127: 31 min 31 out of range please enter integer between 32 , 127: 33 min 33 in range num returned: 33 num returned: 1600375832 min: 1600375832 please enter integer between 32 , 127: 45 min 45 in range num returned: 45 max: 45 

you not initialising 'enter' , assigned in 2 out of 3 of if conditions.

in addition calling function recursively (calling itself), not returning when doing so. maybe intentional, comment after printf makes me think not. recursion why seeing 2 prints.

try this...

int enternumber(int lolimit, int hilimit) {     printf("please enter integer between 32 , 127: ");     fgets(text, lenlimit, stdin);     int enter = atoi(text);     int exit = enter;     if (enter < 32 || enter > 127) {         printf("min %i out of range\n", enter);         return enternumber(enter, hilimit);     }     if (enter >= 32 && enter <= 127 && hilimit > 127) {         printf("min %i in range\n", exit);     }     if (lolimit >= 32 && lolimit <= 127 && hilimit <= 127 && enter >= lolimit) {         exit = hilimit;         printf("max %i in range\n", exit);     }     printf("num returned: %i\n", exit); //prints twice, why?     return exit; }
