Question

How do you alter the following scanf statement in C?

I have the following line of code: scanf("%[^.]s)", string);

My problem is that this terminates the user input after the user enters a period, followed by Enter.

for ex: Enter a string: Today is nice.

How can I change this statement so that user would need to enter a new line, followed by a period and then press Enter so that the input would terminate?

for ex. Enter a string: Today is nice

.

#include<stdio.h>

int main() {

char string[256];

//scanf("%[^.]s", string);

//printf("String which terminate with period : %s", string);

// string will stop with - newline .hence %[^ ]

// then string will stop with period - %[^.]

// then string terminate with newline or Enter key - %*[^ ]

// as this final Enter key should not be stored in string, '*' is used in above constraint.

scanf("%[^ ]%[^.]%*[^ ]", string);

printf("String which terminate with enter : %s", string);

}
