Question

C-language software:

What are its inputs?

What are its outputs?

What decisions does the software have to make?

Answer 1

Below is a c-language software that will prompt user to enter two string (Software's input).

Now this software will compare and decide if the string are reverse of each other or not. (Software's decision)

Finally it will print if the string's are revserse to each other or not (Software's output).

Example:

suppose two strings are dog and god.

now it will reverse one of the entered string let's say first one

than first string will be : god and second is god already.

Now it will compare each character with other string character if all characters are same than it will print string are reverse to each other,else it will print strings are not reverse to each other.

Please have a look of code below:

--------------------------------------

#include <stdio.h>

#include <string.h>

int main(int argc, char** argv)

{

//declare two strings

char string1[100];

char string2[100];

printf("Enter string 1 : ");

scanf("%s",string1);

printf("Enter string 2 : ");

scanf("%s",string2);

//check if lengths are not same

if(strlen(string1)!=strlen(string2)){

printf("The string are not the reverse of each other");

return 0;

}

//now check for each character

long unsigned length = strlen(string1);

long unsigned i;

for(i=0;i<length;i++){

if(toupper(string1[i])!=toupper(string2[length-i-1])){

printf("The string are not the reverse of each other");

return 0;

}

}

printf("The string are the reverse of each other");

return 0;

}

output:
