Hello, the essence of this algorithm is type conversion, and we can use itoa function to realize it. The sample code is as follows:

//Copyright @ Quark

//Date: 20 10- 12-07

# include & ltstdio.h & gt

#define MAX_SIZE 100

# Define Data _ Count4

void main()

{

//Input data

int data[DATA_COUNT] ={ 1，23，456，7890 }；

char shuju[MAX _ SIZE]= { 0 }；

//Convert each plastic data into a string, and then copy it into the shuju array.

int index = 0；

char one data[20]= { 0 }；

for(int I = 0； I & ltDATA _ COUNTi++)

{

Itoa (data [i], oneData,10);

char * temp = oneData

while (*temp！ = '\0')

{

Shu ju[index++]= *(temp++)；

}

}

//Print data

printf("%s "，shuju)；

getchar()；

}
