sscanf - identical to scanf() except that data is from pointer buf in C

//Declaration:  int sscanf(const char *buf, const char *format, ...); 
//Return:       the number of variables assigned.   
                A value of zero means that no fields were assigned.  
                EOF indicates an error.  

  #include <stdio.h>

  int main(void)
    char str[80];
    int i;

    sscanf("hello 1 2 3 4 5", "%s%d", str, &i);
    printf("%s %d", str, i);

    return 0;
