For reading 3 strings
you need a 2D array if you want to store the strings. For display purpose a 1D array of char is enough
char str[3][100];
for(int i=0; i<a; i++)
{
scanf("%s", str[i]); // if you want to store
}
The way you are doing it is overwriting the data of previous string.
// for read and print only
char str[100];
for(int i=0; i<a; ++i)
{
scanf("%s", str or &str[0]);
puts(str);
}
Since you are reading the number of strings to read from user, ideally you need char **str (a pointer to a pointer to char) then read no of strings to read. Allocate memory for that many strings
str = (char**)malloc(a * sizeof(char*));
for(int i=0; i<a; ++i)
{
str[i] = (char*)malloc(100*sizeof(char));//a string of max 100 chars
scanf("%s", str[i]);
}
later free the memory
for(int i=0; i<a; ++i)
{
free(str[i]);
}
free(str);
or you can declare an array of pointers to char char *str[100]; // max of 100 strings. then read the strings
for(int i=0; i<a; ++i){
str[i] = (char*)malloc(100 * sizeof(char)); // each string is of max 100 chars
scanf("%s", str[i]);
}
// later free the memory
for(int i=0; i<a; ++i){
free(str[i]);
}
