Implement a String Copy function in C – which is commonly asked during the coding interview for embeded programming jobs. In C, we use char * to represent the string (char array). And a string is ended with \0 character.
C Implementation of Copy String
The following C function takes a source and copy its content to the pre-allocated target. If the target does not have enough space pre-allocated, a memory access violation will occur.
1 2 3 4 5 6 7 8 | void copyString(char *target, char *source) { while (*source != '\0') { *target = *source; source ++; target ++; } *target = '\0'; } |
void copyString(char *target, char *source) {
while (*source != '\0') {
*target = *source;
source ++;
target ++;
}
*target = '\0';
}
