What's wrong with the code? (solution to The Spy Life) Show several errors. But It runs just fine in other compilers!

Question

#include <stdio.h>
#include <string.h>

char rev(int len, char *str) {
int i, j;
i = len -1;
j=0;
char ch;
while(i>j) {
ch = str[i];
str[i] = str[j];
str[j] = ch;
i--;
j++;
}
}

char rmv(int len, char *str) {
int i;
for(i=0;i<len;i++) {
if((str[i]>=65 && str[i]<=90) || (str[i]>=97 && str[i]<=122) || str[i] == 32) {
printf("%c", str[i]);
}
}
}

int main()
{
char code[100];
int l;
gets(code);
l=strlen(code);
rev(l, code);
rmv(code);
return 0;
}

Answer 1

You probably get a warning for using gets() which you should not be using anyway. Change gets() to fgets(code, sizeof(code), stdin);

rmv() takes an int len argument, but you pass in only the string. Change it to rmv(l, code);

As a stylistic choice, I would probably swap printf("%c", str[i]) for putchar(str[i]) and declare char *str as const in the rmv() function.

Answer 2

In your program have too much errors don't use gets in program in main where u write rmv u passed few parameters first try to fix the bug then try in test case

Answer 3

What kind of error?

Answer 4

Okkk so you have tried to make a code for reversing a string!!!!! I've tried your code. You have made some mistakes. Let me clarify you!!!!
1) you have used "gets" function in your code which doesn't work in this app . You have to use "fgets" instead of "gets" function.
2) you have passed only a single string argument in rmv function while rmv function takes two arguments first is integer and second one is a string.
3) you have declared rev and rmv functions as "non-void" type i.e. char type which are expected to return a char type value but in last you have returned nothing like in a void function. So you have declared rev and rmv functions as "void" type.
I've corrected your code.
Hope!!! It helps.
