Question

Use this code below to creat a code to create a function that accepts 2 strings: the first is a string of text to process;
the second is where the output will be placed. rem1() should remove THE FIRST
occurrence of a lowercase 'x' from the first string, and save the resulting
string in the second arg.

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

int rem1(char*, char*);
int main(void)
{
    char input[120];
    char output[120];
    scanf("%s", input); //stores input
rem1(input, output); //call to rem

printf("output: %s ", output); //prints output

return 0;
}

int rem1(char*input, char*out)
{
   int a=strlen(input); //defines and stores strlen.
   int index= 0; //variable for for statement

for(int i=0; i<a; i++)
{
        if(input[i] != 'x')
{      out[index] = input[i];

        index++;

}
}
return 0;
}

Explanation / Answer

#include<stdio.h>

#include<string.h>

int rem1(char*, char*);

int main(void)

{

char input[120];

char output[120];

scanf("%s", input); //stores input

rem1(input, output); //call to rem

printf("output: %s ", output); //prints output

return 0;

}

int rem1(char*input, char*out)

{

int a=strlen(input); //defines and stores strlen.

int index= 0, count = 0; //variable for for statement

for(int i=0; i<a; i++)

{

if(input[i] != 'x' || count != 0)

{   

out[index] = input[i];

index++;

}

if(input[i] == 'x')

count++;

}

out[index] = '';

}
