Char type is 1 byte integer. As long as the value is in the range of 1 byte, 1 byte can be stored.

For example:

char s[ 10]={ 3 1，32，33，34，35，36，37，38，39，40 }；

int I； for(I = 0； I< 10; i++) printf("%d "，s[I])；

Output: 3 1 32 33 34 35 36 37 38 39 40

In addition, you can also store integers as strings:

char s[ 10]= " 1234567 "；

int I；

sscanf(s，" %d "，& ampI)； //Convert to an integer

printf("%d\n "，I)； //output i.

In addition, the binary integer 16 can also be stored as a string. You can use the strtol () function to convert it to an integer. I won't go into details here.
