怎么把数字变成字符串比如已经存在的123要变成字符串要怎么写

Question

比如这串代码：
#include
#include
#include
int main( )
{
char a[10000];
int i,j,n,s;
ges(a);
n=strlen(a);
for(i=0;i<n;i++)
{
s+=a[i];
}
我要把得到的s变成字符串？求帮帮忙。

Answer 1

使用 sprintf 函数即可。

 #include <stdio.h>
void main( void )
{
char  buffer[200], s[] = "computer", c = 'l';
int   i = 35, j;
float fp = 1.7320534f;

/* Format and print various data: */
j  = sprintf( buffer,     "\tString:    %s\n", s );
j += sprintf( buffer + j, "\tCharacter: %c\n", c );
   j += sprintf( buffer + j, "\tInteger:   %d\n", i );
   j += sprintf( buffer + j, "\tReal:      %f\n", fp );

printf( "Output:\n%s\ncharacter count = %d\n", buffer, j );
}
Output
Output:
String:    computer
Character: l
   Integer:   35
   Real:      1.732053

character count = 71
