python和C语言的互转

Question

Python转C语言

para = "Letting go of a negative habit happens by making one positive choice at a time. " \
       "Creating a desired achievement comes about in the same way."

para = para.split()
arr = []
num_a = 0
word_num = 0
word_line = 0
count_line = 0
max_line = 72

for p in para:
    if p == 'a':
        p = "//"+p+"//"
        num_a += 1
    word_num += 1
    word_line = len(p)
    count_line += word_line
    arr.append(p)

arr = ' '.join(arr)
print(arr)

输出是

Letting go of //a// negative habit happens by making one positive choice at //a// time. Creating //a// desired achievement comes about in the same way.

Answer 1

判断句子中的a即可

#include <stdio.h>
#include <string.h>
int main()
{
    char t[]={"Letting go of a negative habit happens by making one positive choice at a time. " 
       "Creating a desired achievement comes about in the same way."};
    int len=strlen(t);
    for(int i=0;i<len;i++)
    {
        if(t[i]=='a'&&i-1>0&&i+1<len-1)
        {
            if(t[i-1]==' '&&t[i+1]==' ')
            {
                printf("//%c//",t[i]);
            }
            else
            {
                printf("%c",t[i]);
            }
        }
        else
        {
            printf("%c",t[i]);
        }
    }
    printf("\n");
    return 0;
}
