Hi, could someone please help me with these error messages? It's not compiling properly in UNIX. My code is as follows:

#include #include

int main() {

char input[100]; printf("Enter your desired string of characters: "); gets(input);

int len = strlen(input); printf("The length of the string you entered is: %d ", len);

char output1[100]; strcpy(output1,input); printf("The copy of the string you entered is: %s ", output1);

char output2[] = "Copied String is -"; strcat(output2, input); printf("The Concatenated String is: %s ", output2);

strrev(input); printf("The reversed string is: %s ", input);

strupr(output2); printf("The String in Uppercase is: %s ", output2);

return 0;
