What is the C programming code to reverse a input string?

Answer 1

{

// get input

char input[256];

gets(input);

// reverse it

char reverse[256];

strReverse(input, reverse);

}

// reverses str and puts the result in buff

// NOTE: buff must be at least as large as str

void strReverse(const char* str, char* buff) {

const int length = strlen(str);

// special case for zero-length strings

if( length == 0 ) {

return;

}

// reversify

int i;

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

buff[i] = str[length - i - 1];

}

buff[i] = '\0';

}
