void BuildString(int argc, char* argv[]);

1. Arguments passed through the function. Concatenate the strings arguments using strcat, display the concatenated string.

2.. If only one argument passed, display the string.

3. If no argument passed, display the message, no argument passed.
In main do the following:

1. Call the function BuildString, passing the proper arguments (argc and argv).

Answer 1

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

int main(int argc, char *argv[])
{
int i, length = 0;
char str[100];
if( argc >= 2 )
{
strcpy(str, "");
for(i = 1; i < argc; i++)
{
strcat(str, argv[i]);
}
length = strlen(str);
str[length] = '\0';
printf("Final String: %s\n", str);
}
else
{
printf("argument list is empty.\n");
}
return 0;
}

Output:

Final String: ab
