在C中将整数数组转换为字符串

Question

int arr [] = {2,54,87,9,132,6};     我希望将并排数字转换为C中的单个字符串。

like 2, 54 ==>converted into 254

 87,9  ==>converted into 879

 132,6 ==>converted into 1326

Answer 1

执行以下操作：

for(i=0; i<n; i+=2) {
    char s1[20], s2[20];
    sprintf(s1, "%d", a[i]);
    sprintf(s2, "%d", a[i+1]);
    strcat(s1, s2);
}
