如何在C中以整数类型数组作为输入的前缀？ 当我使用％[^ \\ n]输入字符串时

Question

Hey i am a new bee in c programming.... I have faced the following problem...

#include<stdio.h>
main(){
  char line[80];
  scanf("%[^\n]",line); /*here i say it is terminated when new line encounterd*/
  printf("%s",line);
}

This code work for taking string input in a line and also force scanf to take input with space...

#include<stdio.h>
main(){
    char line[80];
    scanf(" %[ ABCD]",line); /*here i say when program encountered anything without blankspace, A,B,C,D it is terminated*/
    printf("%s",line);
}

here an another code which take only blank space and 'A','B','C','D'

if i want to do this job in case of integer type by using this what can i do?

Answer 1

try this:

#include <stdio.h>

int main (void) {
   int i;
   printf("Please enter a number: ");
   scanf("%d",&i);      /* Waits for input.    */
   printf("You entered %d\n",i);
   return 0;
}
