How to take an input string containing a sentence with spaces in C programming
We cannot use the scanf() function since after the first space, other part of the string will be neglected. If gets() fuction used it says buffer overflow.

Use fgets to prevent overflow... It takes 3 parameters...
fgets(char *str,int n,File* stream) for ur case if ur array name is str, and u want to input 30 characters to be stored from console use...
fgets(str, 30,stdin) ;

You can use `scanf` too, but care needed to be taken to prevent buffer overflow.
// allocate 50 characters + 1
// for the string terminator
char buffer[51] = {0};
// Read up to 50 characters into
// <buffer> or until a \n is found
scanf("%50[^\n]s", buffer);
printf("%s\n", buffer);
